I read this again to see even a little teeny tiny thing that could make me not hate Jaekyung so much (couldn't find one btw), that scene where he uses the toy was something I had to skip over. I felt physically uncomfortable. He's a selfish brick that's for sure, but also know that he's gonna change. Not that I'll personally will like him more just because he's gonna change at some point, but I'm excited to see this monster dick suffer. One of the tags of this webtoon is regretful seme, so I hope shit is gonna go down real good for Jaekyung (╬ ̄皿 ̄)凸
This last chapter was ridiculous now that we're talking about his dick, when he tells Dan to suck it... bro that thing would go through Dan's skull if he shoved the whole thing in. Weapon of mass destruction.

Also
The writer really has no idea about human anatomy. Jaekyungs dick is literally the size of a baseball bat and its supposed to poke into the stomach...girlie thats not sex thats an assault and that will literally rupture his intestines
