Sara is casted/Ee Jung's brother
Sara/Cha Eun Jae will be played by Park Soo Jin
Ee Jung's brother, So Eel Hyun will be played by Im Joo Hwan.
i don't know either of them. but Sara is cute, and Ee Jung's brother is hot like him, so i'm cool with it.
what i'm not cool with is what they're doing with the story between Sara and Ee Jung. from allkpop:
Eun Jae was Yi Jung's childhood friend who loved him, but was unable to carry out that love and ended up with his brother, So Yil Hyun (played by Im Joo Hwan), instead. But through her, Yi Jung's hidden side is revealed as someone who is pure-hearted and earnest.
say what?! awww man. i like drama, but this.. no. i was already getting annoyed wit the Ga Eul/Ee Jung storyline, but now that they've veered from the manga and had her switch over from Ee Jung to his brother... no. some how, this makes that love story less pure feeling.
