If you can't realize that "kid" is being used to describe someone younger and irrational, rather than an actual minor, you shouldn't be reading this. Gyuwon is 23 years old. Accusing Woonha of being a predator makes no sense when Gyuwon is the one who raped Woonha in the first place. Woonha wasn't even paying attention to him before that.
I’d call this rage bait, but I've seen this exact lack of reading comprehension and media literacy from people who probably aren't ready for mature content. These comics have age ratings for a reason, and your comment is exhibit A.
