I don't get what was the point of that last part. Like, at the beginning it was all about empathizing with Shin and understanding how he turned out this way, and that's okay, I get it. But the way that the author decided that it was a good idea to make him find his true self and to be able to recognize what he has always yearned for through r4ping the only person that stood by his side, the one he has been treating like sh1t since the beginning, it's simply disgusting. And that whole purity thing is weird. He got his character development through harming deeply someone he was supposed to care for, at least a bit. The worse thing is that even in the future he doesn't feel any guilt. It's like " I had a tough childhood, so now I have the right to do whatever I want with the rest". Disgusting
