To be fair, he's literally drugged up with stimulants. Better to relieve his horn dog. Plus when in a state of arousal, especially with stimulants your body is pumping a sh** ton of happy hormones.

Well to be fair that's like every male in their 20's. They're all sh**.

You sound dumb as fu**. Have you not read the story at all? Lacks character development? Mf, the book aint even finished yet. There's literally been a drastic character development in Ho-in already. 

Also, not every single character needs a character development. This is merely just focusing on the romance between these two boys, and chunwoo learning what he deserves and letting go of his first love who has his own  personal issues to work out. Like wtf do you except? Neither of them experience any traumatic experiences during the novel to create such a drastic change in their development like you want it to. Sit yo a** down guy.

It's not that it's not enough. You're seeing it wrong. The issue at hand is Si-eon doesn't know how to show love other than doing acts of kindness and service because that's how he grew up knowing love. He was never shown proper love, and the most important thing, selfish love. Therefore he can't selfishly love either and he's given up / grown numb to emotions of love and affection. Which is what now is the issue with all his relationships. He's given up, has such low self-worth, and cannot selfishly love which causes all these issues on his partners side. At this point, if he can't make them happy with his love language, and has given up on being vulnerable and trying to love with all his trauma regarding relationships, what's the point of keeping them trapped with him? Why should he selfishly keep them around if they aren't happy with him? He knows they will be happier without him. Or so he thinks.

they're idiots. what can you expect from humans at this point?

You're missing the point headass

mood. i can fix him.
