SPOILER :
Hwan definitely had something to do with the ML parents death. WTF, I thought he was a good guy that loved the ML. Turns out he’s an obsessed psycho, that wants to possess the ML. I know for sure this dude is going to go bat shit crazy, after ML breaks up with him. Poor Jin, at first I didn’t know who to tie him too. Because they were both seemingly nice guys, in love with them ML. I definitely wanted his to stay with Jin now. But Jin is gone, & the ML is once again on his own. Just throw this disturbed psycho in a psychiatric ward, & move on.
Your wish is my command
