Cho-ah is not at fault for his current situation, and if half the stories fanbase was of age to even be on the site and actually read the story, you would know that. Read chapter 10. Then go and read when Mujin's old lover shows up. Even before the g** took over, he was still horrible and took advantage of Cho-ah. Y'all wanna bring up Cho-ah and his old love interest constantly, but seem to forget that Cho-ah was backed off a cliff with memory loss. Cho-ah is not a sl*t for getting r*ped. Mujin and just about everybody else in this story are people you should not aspire to be like. And no amount of trauma excuses his actions.
Again, don't know what it is with this 2012 mindset of every anime fandom where the weaker gay man or female characters are the worst but the male characters can commit the most horrible atrocities while looking ugly and yall will defend everything.
