This is such a well written manhwa! The pain and frustration are so real!
There's a real Minho anywhere in life. People like him are so used to being the main character they paraded as the victim while manipulate and doing harmful things to people around them. Usually people like him are powerful enough to put people in their grasp and control every aspect of their life. Minho needs Woojjn not because he loves him. He considered Woojin as part of his own belonging and he was so used to have an obedient Woojin, so any sign of he's being out of control scared the shit out of Minho. That's why he obsessed over Woojin.
Woojin has been the victim of manipulation all of his life. Even though he complicates Taehwan's life, but if their love and sympathy are strong enough, they'll have the best relationship and will thrive to be the best person for each other.
I hope Taehwan would strong enough to fight for Woojin, and vice versa. And Minho should just go to hell.
Yeonjo I hope you'll get your revenge, but I have a feeling that the mc will do something in yeonjo's favour. Maybe it will have something to do with this new character lurking in the horizon
