Dong Kyu has called Su Ha to talk to her about something. He says there's a party this weekend and she'll have to come with him. She asks if that's the right thing to do, since she's is Chan Min's assistant. He says Chang Min has nothing to do with this party and says they don't have to worry about work since it's the weekend. He asks if she minds working on the weekend and she says she's fine with it. Then he says the party is actually for couples. Su Ha asks if he wants her to act as his girlfriend. He says that's it, he wants her to be his partner. He says to think of it as work. She agrees and Dong Kyu seems shocked that it's so easy. Chang Min overhears Su Ha saying that she will be Dong Kyu's girlfriend.
Chan Min calls Su Ha and asks where she is. I think she's about to tell the truth but Dong Kyu whispers to her to not tell. Su Ha seems unwilling to lie but later says she's in the bathroom and hangs up. She demands Dong Kyu why he wanted to hide where she really was and Dong Kyu says Chan Min only thinks of himself so if he found out that his assistant was working for another person, he would be angry. Su Ha says that's true, since Chan Min has the prince syndrome and he pretended she was his fiancee before. Dong Kyu says so she should definitely not tell about her acting as his girlfriend for the party or else Chan Min will be really upset.
Later Dong Kyu goes to the bathroom and curses himself for saying bad things about his little brother (Chan Min). In the bathroom stall, Manager Kwak wonders why Dong Kyu is cursing himself and wonders if Dong Kyu and Chan Min are having problems. He reports to Chang Min's mom and says something seems to be up with Dong Kyu and her son. She asks why and manager Kwak says it's probably because of Lee Su Ha. Because she assigned Su Ha to be the assistant of Chan Min, Dong Kyu's chances with her became smaller. Manager Kwak says once love is in front of you, family doesn't matter. She seems to find this amusing and asks if that's how it is with manager Kwak. He asks if she's making fun of how he and his two other brothers haven't been able to get married yet. She says that's because of his lack of skill. She says she can trust Chan Min to be good at dating and manager Kwak says if there was an Olympic event for such a thing, Chan Min would definitely get a gold medal, although that gold medal isn't something good to show to others. Chan Min's mother gets angry and he apologizes, saying that he was jealous of Chan Min's skill and says if he had Chan Min's skill, he could've been married 12 times.
Su Ha apologizes for leaving the office without telling him. He asks her if she feels good after going to the bathroom. She says of course and he says he'll make her feel even better and tells her to come along. Su Ha almost collides with a guy who is pushing a cart of boxes but Chan Min saves her and tells the employee to be more careful next time. She says she's fine but Chan Min says he's responsible for her from head to toe during working hours. The aunt and grandfather are watching from afar and the aunt says Chang Min is a real player. Her father wonders where he got that from and she says of course it's from him. She wonders if it's okay to leave it like this, since it'll be hard to let Dong Kyu have a chance.
The aunt and grandfather are eating mandu (steamed dumplings) and he complains about how bad the mandu is. He asks which company made them and his daughter says if he finds out he'll be hurt. It is actually made by their company and the grandfather says there's no point in living anymore; his company can't even make good mandu and his grandsons aren't dating the way he wants them to. His daughter asks if he's not dating anymore. He says he's too old for such things and she says before he said women are the best parts of life and other things and he says he never said such things but then a beautiful woman walks by and he stares at her admiringly. He remembers the woman he was in love with long ago and his daughter snaps him back to reality. She asks if she should introduce a woman to him and he says he isn't seeing women anymore and walks away. She says she'll take him anywhere he wants to go and they should go out on a date. He says to stop doing weird things and says even if he sees no point in life, he won't die so she shouldn't do things she's not used to. He wonders where Chan Min took Su Ha and says he feels suspicious. The aunt says there's no way he could've taken her somewhere weird but they're both suspicious.
Su Ha asks what this place is and he says they're getting a massage. She hears a man groaning and says she's really disappointed at Chan Min's behavior. She asks him if she looks that easy and says she really has lived her life honestly. He asks her what she thinks this place is and she says even though she's lived in the countryside she knows modern things. He opens the door to their room and she finds that it's actually just a massage place. Chan Min asks her what her relationship is with Dong Kyu. She says she's already told him that they're nothing. He says it doesn't matter anyway, since he'll make her his. He tells the massage people to go now and asks Su Ha what she's doing this weekend. She says she's busy and he asks if she's dating. She says no (a bit too quickly, in opinion) and says she has to work.
On the boat to the island, Su Ha's learning how to greet foreigners in English, Chinese and Japanese. She asks Dong Kyu if they have to practice acting as couples and points to a couple who is hugging each other very tightly and says they should act like them. She's freaked out when Dong Kyu even comes close. Then the couple starts kissing and she becomes indignant at the show of improper behavior and walks away.
Su Ha's cleaning the house and practicing greetings and wonders where everyone is. Dong Kyu is looking for people but sees no one around. Dong Kyu tries to call his grandfather, who doesn't pick up his phone and merely wishes his grandson good luck. Su Ha wonder if the grandfather got the wrong date and Dong Kyu says his grandfather is not that time of person. Even though he was a servant to Su Ha's family long ago, now he is a real sharp businessman. Su Ha asks why Dong Kyu is getting so angry and says she's going out. He asks where she is going and says she should clean or cook, since she didn't come here to play. She says she came strictly for work reasons and if for play she wouldn't have come anyway. She says she's already finished cleaning and says she can't make anything when there's no food. Dong Kyu wonder why she's getting so angry. She's walking along and sees a bunch of kids getting clams. She imagines all the guests eating the clams she's brought and loving it and she happily gathers clams with the kids. Meanwhile, Dong Kyu calls manager Kwak and asks when the president is coming. Manager Kwak says he got a call saying the president will come soon. Dong Kyu asks if manager Kwak is coming to the island that he is on and manager Kwak says that's the wrong island. Then the president enters to manager Kwak hangs up. Dong Kyu hangs up and wonders what happened. Then he realizes it was his grandfather's plan to get him and Su Ha together.
Dong Kyu runs to Su Ha, who is waving goodbye the kids who are leaving by boat and tries to tell her to stop the boat but she can't hear. Once he reaches her, the boat is gone and Dong Kyu says they should've left with that boat. Su Ha realizes that they are stuck on the island until tomorrow and wonders if Dong Kyu did this on purpose. He demands her why she makes him look so guilty and says he tried to call her many times but she wouldn't pick up. She finds out that she left her phone in her bag and Dong Kyu says she should pay attention more. She asks if there is no way and he asks if she wants to swim to shore and she say no. They are on their way back home when they hear a howl. Su Ha becomes afraid and sees Dong Kyu's face as a wolf's and screams and runs away. She goes to the house and doesn't let Dong Kyu in. He says he'll stay in the living room and she can go into one of the rooms and she says the rooms are all locked and says he should just sleep outside and she'll give him a blanket. Then she sees a shadowy figure walking in the window and screams and opens teh door, letting Dong Kyu in. Dong Kyu doesn't go out and Su Ha is afraid. Meanwhile, a man blocks the door so it can't be opened. He calls the grandfather says the operation has been successful. The grandfather says it's time for step 2 and tells teh man to watch carefully.
Chan Min comes to the grandfather and asks if he's working even at a party. He says no and asks Chan Min to be is escort for tonight. The aunt sees this with Chan Min's mother and says Chan Min is acting pretty good. His mother says it's because Chan Min hasn't really been into it but once he does, he does things perfectly. Then she asks where Dong Kyu is, since usually he doesn't miss these kind of events and the aunt says he is in an important mission.
Su Ha and Dong Kyu are hungry and sees a ton of food on the table. Su Ha says she didn't see it before but they're both happy to see some food.
Chan Min tries to call Su Ha many times but doesn't get a response. His grandfather calls him and he hangs up the phone.
Su Ha is drinking and Dong Kyu asks if he should pour more liquor for her. She says she cannot have a man pour her drinks as it is improper. Dong Kyu tries some and says it's so bitter. She says Dong Kyu can't even drink like a man and he says she can drink like one. She says during she had to attend alot of ceremonies for dead ancestors and each time there is alcohol she has to drink it all since that's food, too. She wonders what kind of liquor this is since it's so nice. The grandfather is drinking his wine and talks to himself that that liquor is said to make you active during night and bids Dong Kyu a success.
Su Ha takes off her red jacket because she's so hot and she's looking at Dong Kyu and tries to find her senses. Dong Kyu wakes up and runs away from Su Ha. The worker hears them from outside and calls the president and says it's a success. The grandfather is ecstatic. Su Ha wakes up and imagines what happened that night. In her mind Dong Kyu is about to attack her. Su Ha asks Dong Kyu how he can do such things to her. Dong Kyu says she's the one who threw herself at him. She asks why he didn't run away. He says the door couldn't open but the door opens very easily now. Su Ha becomes more suspicious. Su Ha boards the boat prevents Dong Kyu from getting on. The boat starts to move and Dong Kyu is left dangling. They try to save him but he falls into the water. Su Ha apologizes for leaving him like that.
The grandfather tries to call Dong Kyu but can't get through. He wonders if it's because Dong Kyu is too tired from last night. Then he gets a call from the worker at the island who says Su Ha left by the boat in dawn and Dong Kyu left on the boat after. The grandfather tries to call Dong Kyu again but can't get through. The phone is broken because it was in the water. Dong Kyu wonders how Su Ha forgot everything so clearly just because she was drunk and says one day he will revenge her.
Su Ha answers her phone and Chan Min asks why she isn't at work yet. She said she had trouble getting on the boat home and says she's coming up as soon as possible. Chan Min wonders what work she is talking about on the island and says she has weird excuses. He tells her to come quickly and hangs up as his grandfather enters. His grandfather says he should take down pictures of himself in an office and asks if Su Ha is here yet. Chan Min says she's late and says he'll scold her once she's here. The grandfather says to let her be since she must have had other business and asks if she's coming to Seoul now. Chan Min asks how he knew Su Ha wasn't in Seoul and he says he's just saying. They go out together to get coffee. Manager Kwak reports to Chan Min's mother saying that he heard the grandfather saying he will go out to lunch with Chan Min and Su Ha later and Chan Min's mother says she didn't know Su Ha would prove to be such a valuable card to play.
Su Ha's friend asks Jun Hee why she doesn't come to work together with Su Ha and Jun Hee says Su Ha didn't come home last night, because she was away for work but she is suspicious since even manager Kwak didn't know about that. Jung Sook (Su Ha's friend) wonder if Su Ha has a boyfriend but says that's impossible since even she is solo right now. Jun Hee says there's a saying that sly cats get taken first. Chan Min comes in then and asks who is a sly cat. He says it's probably not Jun Hee and looks at Jung Sook. Jung Sook says there's no way she is and says in her family, you can't pretend to be away for work while you're out with another man. Chan Min works to put the pieces together. He asks manager Kwak to find out who went to an island for work and manager Kwak says he will search for that information and asks if Chan Min knew that Dong Kyu accidentally went to the wrong island this weekend and wonder how he made that mistake since Dong Kyu is not that kind of person. Manager Kwak is looking for the information that Chan Min wanted and finds no results. He practices saying his failure in front of Chan Min's office and enters but finds no Chan Min.
Chan Min asks if his grandfather planned it all. The grandfather feigns innocence. Chan Min asks if his grandfather wants Dong Kyu and Su Ha to be together since she is from the house that his grandfather was a servant to. He asks Chan Min how he knows that and Chan Min says times have changed. The grandfather says no one will understand how, even if he has alot of money, he really wants to go to that place but he can't and he can't see the person he wants to. Chang Min says he'll make his grandfather's wish come true and asks for equal opportunity in the game. He wants equal chances as Dong Kyu to have Su Ha. Chan Min says his grandfather should go to Hwa Ahn Dang himself and go see the people as the president of Top Group (to thank them for letting the group use the place for the advertising shoot?)
Su Ha is going to work in a hurry when Chan Min and his grandfather tells her to get in the car. Su Ha and the grandfather are singing old songs and Chan Min says those songs don't match the fancy car but they continue to sing. Su Ha asks where they are going anyway and says she just got in because they told her to. Chan Min says they're going to Hwa Ahn Dang and Su Ha tells them to stop and says she has to go really badly. She calls Dong Kyu's cell phone but remembers it's probably broken since he was in the water. She calls his office and Dong Kyu is angry with her at first but finds out that his grandfather is going to Hwa Ahn Dang. Meanwhile, Chan Min and his grandfather wonders why Su Ha isn't coming up and Chan Min says he'll go and chekc on her. His grandfather says he knows Chan Min's motives and says he'll go down instead. Dong Kyu is telling Su Ha to stall for some time and she asks how she can and rolls down the steep hill to get some time. Chan Min and his grandfather try to go down the hill but both are afraid and the grandfather blames his arthritis for making him so stiff. Chang Min tries to go down but he's not very successful either so the grandfather calls 119 (the Korean version of 911)
Dong Kyu calls Su Ha and says he'll be there in an hour so he tells her to stall for some time until then. Su Ha says she can't and grabs on to the tree branches to prevent herself from being pulled up. But in the end she is pulled up.
Hwa Ran is in a conference with Chan Min's mother and manager Kwak. She proposes to make Hwa Ahn Dang a tourist area where tourists can enjoy the beach in the day and enjoy the cultural richness of the town in the evening. Both people seem impressed with the idea and manager Kwak says the president has a special connection with Hwa Ahn Dang. Chan Min's mother stop him and tells Hwa Ran to prepare for the presentation of this proposal. She scolds manager Kwak for being careless. She says his common sense is as lacking as his hair and he asks her how she can be so harsh. She tells to find out immediately where Chan Min is.
Meanwhile, our adventurous trio have reached Hwa Ahn Dang. The grandfather tells Chan Min to buy some things to offer. The old man there is watching the president with Hwa Ran's mother and suspects who the president really is. The grandmother prepares to serve the president some food. The president is looking around when the old man starts attacking him. Dong Kyu protects his grandfather but ends up getting hurt. People are trying to stop the old man when the other people at Hwa Ahn Dang finds out that the president is actually that cow thief from long ago. The president begs for forgiveness when the old man gives the scythe (?) to the president and tells him to catch him. The president is kicked out by the grandmother. She throws salt at him and tells him to never return. Chan Min says he'll make sure his grandfather can return one day.
Dong Kyu and Su Ha are inside and she says she doesn't want to help him when she thinks about last night and he says it was her fault. He says it hurts and she asks if they should go to the hospital. Dong Kyu says it's fine since it's only a light scratch. Su Ha wonders how her grandfather can still remember something like that from 50 years ago and Dong Kyu wonders if they should buy a few cows as replacement. Su Ha says those cow cannot replace that cow. The grandmother gives them mouse dung to put on his wound. The grandmother is upset about how things went.
In the car ride back to Seoul, Su Ha is avoiding being next to Dong Kyu when she remembers what happened last night (but Dong Kyu doesn't know she remembered). They get a call that the president is unwell. It seems that he collapsed from shock. Once they're out of the room Chan Min asks Dong Kyu about Su Ha. Dong Kyu says now is not the time to think about her and asks how careless Chan Min was to bring their grandfather to such a place. Chan Min says he didn't know the situation was like that and says his grandfather should have stolen a chunk of gold or money since he is going to be hated anyway. Dong Kyu says their grandfather is an old man who has blood pressure problems already and asks Chan Min what he's going to do if his health gets worse because of this.
Su Ha is upset about what she did last night. She tries to forget that it happened but can't. Jun Hee finds her and says she's playing around while the house is in chaos. The elders have arrived. They found out that Su Ha is working for the former thief. Her father apologizes. They say they understand how hard it is for a weak female to guard Hwa Ahn Dang. They seem to like Jun Young. They ask how he thinks of the place that Su Ha holds right now. The mother agrees and says it's tough for Su Ha to do such a difficult task and Jun Hee says such a place is not good anyway since no one will recognize it and the elders are displeased. Su Ha excuses herself and says she will follow whatever the elders decide on. Jun Young says he has something to tell them.
Meanwhile the president demands to know why they treat him so harshly for something that happened 50 years ago. He refuses to be defeated. The aunt comes in and asks if his blood pressure is going up again. He tells her to bring everyone.
Jun Young tells the elders that Su Ha is 22 now and the same age as Jun Hee. He says nowadays people are more like Jun Hee and he is the same. He says if they are to kick Su Ha out from the place then that house will become one without an owner. He says he does not want that spot.
Meanwhile the president is making an important announcement. He says he will hand over the president spot at the company to whoever brings him Hwa Ahn Dang.
Jun Young goes to Su Ha and asks if she's okay. She says the elders are right and she has no right to have the place. She says Jun Young should take that spot. He says if he were to take that spot, he'll sell the place. He says Hwa Ahn Dang is meaningless to him so he'll sell it. Su Ha seems shocked. He asks if she'll be okay with that.
