I get why Trash would seem attractive...specially to Na Jeong, I mean, they've been living like siblings their whooole lives! You're bound to get very close to someone like that and even develop feelings for them, like it happened here...I like some of trash traces, like I think he's gonna be an awesome doctor and how he actually looks out for everyone...so, it's not about the looks (although I don't think he's ugly) but everything together makes him an actual and real good person..
But DAMN, that childish behavior and all those things he does to trying being cute!! I don't get them, i'm sorry, but I don't get them! And even though I get getting attracted to Trash, I would never be able to have him as a boyfriend..I would go insane, seriously, with all the childish and them suddenly SUPER serious stuff...I don't get it!
About the romantic scenes with CB, I'm not sure I would call them "romantic", but they give the more romantic feeling than the Trash scenes...They're always super cute and really meaningful and you just can see CB's heart being broken E-V-E-R-Y single time, I think that's why they have a much more "intimate" feeling to them than Trash's scenes.
Totally off-record, DAMN, Yoon Jin is cute!! I wish I would look that good with those lipsticks XDDD
