Its rape were talking about , a person who was raped would be petrified and feel sick being in the same room as the rapist , but since its a manga i dont expect that , but he didnt have to bow to him , he would at least be angry.
They would have talk at some point even without his help, and thats not a good reason to forgive someone who raped you.
Hi! I'd just like to point out that Jaerim was never actually raped. It was sexual assault, which is still awful, but not the same. Also, not all rape is the same and not all survivors are the same. Yes, some feel the way you described, but some others don't. Please don't generalize! It makes coming forward harder for survivors that don't have strong reactions like that.

I like the story and all but the first thing you say to someone who raped you is "Hello" and you bow to them ??? Wtf
