Continuing to love this because rather than a generic "Minho was abused and is now abusive" we're really getting into the nitty gritty of his flavor of toxicity now.
Minho with his skyscraper sized control issues feels like he can only safely show affection when he is somethings whole world (like a puppy, or traumatized kid with no boundaries and poor self-regulation). But when he gets reminded he doesn't have control (puppy dies, kid seeks comfort with someone else) he literally loses his sense of self and spirals.
To reclaim control he thinks he needs to prove he doesn't care, but what he's actually doing is trying to prove that he IS the center of Woojin's world. He enjoys watching him get upset/devastated because it proves that Woojin only has him which helps feel safe keeping Woojin around (because again he only feels safe giving affection to something he feels he can control). He also needs to degrade Woojin because him having self-worth would mean he'd have something outside of Minho. Can't have that.
When so many problematic BL characters feel like such caricatures "I'm evil/abusive cuz...I was lonely or something" this is refreshing
Uh oh Minho you're losing control, time to act unhinged like you always do.
This is why IRL people are advised to just leave abusive situations. Preferably when their abuser is away and with a safe persons support, no confrontation, closure is for therapy.
But that would be waaaay too safe & sane for this Manwha and I'm here for the drama.
My guess...maybe confinement? We were like 60% there already ╥﹏╥
