If Shi Won/Yoon Jae isn't going to happen, I am Joon Hee/Yoon Jae all the way - this scene killed me:
The look on Joon Hee's face when the oblivious Yoon Jae is hugging him like that! I feel awful for Joon Hee because he has zero chance of his affection being returned - things look grim for Yoon Jae because Shi Won sees him only a a friend, but at least they share a sexual orientation. No matter what, Yoon Jae isn't going to be anything but straight so there is no chance for Joon Hee at all.
And you know what makes it super-delicious? Yoon Jae totally thinks Joon Hee likes Shi Won and is wildly jealous of them together:
Oh, kids! I just want to feed you all and pat you on the head and say everything will be OK.
