You're naive. It's not because you're psycho or possessive, obsessive that you can't be a good father. It's because of this that a lot of people like him doesn't get really punished, and doesn't really face to his acts because they can be possessive, obsessive and be a good father. If you see in this character complexity ... So you didn't see a lot of good and complexe characters in your life... And let other read and criticize whatever they want, they have right to say "I don't like it" like you said "I like it" comment are here to say the truth : there are people who like it and other person's who don't like it. And it's because we aren't not agree with you that we didn't get "the complexity of the characters" this is just YOUR opinion, so stop to think that YOUR opinion is the truth thanks.
Hahahah chill~
It's true that it's my opinion. What I'm trying to imply is that people who talks shit about it can leave. They can criticize it, but they shouldn't go around judging people who likes to read it.
It just kinda ticked me off when there are readers who wouldn't just give their critisms and leave it at that. There are those who also include the readers as if implying that there's something wrong with other readers for liking particular stories that aren't openly accepted by the wider society.
Sungyeon is a perfect example of a man who does not give in too much to his ID..... He rationalized with his ID EGO and SUPEREGO.... Most characters who has some ridiculous possessive and obsessive streaks go psycho wacko... But this guy.... He made himself a competent husband and father.... Other shit bags would either be good in one and fail on the other or fail in both....
So if you don't get the essence of his character, beat it! Go read other stories and widen you're perspectives, maybe then you'll get the complexity of his development as a character!!!
