I really liked his character, he only raped him at the end after being treated so poorly by cho-ah that he lost it and handed himself over to Sura, I think he had little control over his emotions and self after that. I think he was so starved of love, he wanted to be loved and live a normal life so much, he stayed with the first person that showed him the smallist sign of affection and he clung to it. Biryu deserved better than Cho-ah and a better outcome.

Am I the only one who never liked cho-ah? He was a nasty person most the way though, only ever thinking of himself and his needs. His father tried to murder Biryu, he was right to kill them, I'm just pissed he still wanted to be with cho-ah...
