Yeah it's called development. Not transformation. Development is slow. Development follows a gentle trajectory because humans don't change overnight either. But ML though is a bit a cranky, is fine with MC having a social life, overnight trips, friends and just general fun. From going to that to this is not only cognitively dissonant, but really.my main focus was on the cliched nature of the plot turn, the oft repeated trope that authors seem to think is romantic and not psychotic. Manhwa bl authors have a very fucked up understanding of romance and its conflicts

Wow author. So the ML wants to keep the MC as captive? How nouvel! Is he threatening to break his ankles? No other ML has ever done it in any bl ever, yay! You are so smart and imaginative. What a creative and sensical solution to a conflict, never seen before in the genre! Thanks for bringing something new to the table, I will make sure to smash it with a stone. :)))
Dropped.
