@Ketchup yea..
Spoiler!
that he realized in the end that he experienced all those because of his wrong decisions. he even told it himself in some chapters (almost ending) .. i didn't even say that ML didn't do anything wrong and i kept on saying that in my other comments. and if you're understanding the whole story and not just focusing on the ra** part that the MC not even caring the part ML raping him before. that's not even the reason why he left for the second time. read more so you can understand what's the author trying for the readers to see and understand. they both did something terrible to each other. not because it's only the pov of the MC we are seeing here the ML didn't experience something terrible. even Joonyoung said it himself in some chapter while talking to the MC.
