i think that kwon didn't really care about they parents being together and i didn't want him to fall for eun tae-hee it mad me mad cause he should have ended up with choi. and some of kwon action where stupid like how he said to choi "stop using are friendship as a weapon" what! if you never wanted to do any of those things she told you to do then don't do it. 2 you shouldn't have told choi that you will marry her and she just wants to help you. kwon is a big baby and he cry's over everything and choi was never in the wrong, choi can be a bit arrogant but she's understandable and i know how she feels .i don't like how tae-hee came out of nowhere and ruined things some may disagree but i really didn't like that. choi is really nice deep down but she had a lot of bad things happen to her so that's why she's always set on revenge and lee se-joo didn't really help at all he kinda made things a bit worser because i knew he knew that kwon was falling for tae-hee and he could've prepared choi so she wont get hurt that's what really upset me but its just my opinion.
