the main character's personality and the character in "we are dating now" are completely different. :O i like him better in we are dating now. but he's a good actor.
i don't think he is her real son.. otherwise she would at least feel something towards him... btw.. yoon and his mother are so stage performer.. mortifyingly funny
I guess Moo-Hyuk is a little angry of his birth mother and Jealous of his brother who got all the love from the mother, that's why he let Yoon almost drown in the pool..
at times i find myself saying, oh that's so cute haha with the swimming, shower, and magnifying glass scenes. then it starts getting super sadd ='/ this drama puts me on an emotional rollercoaster lol (:
