It's surprising how far Arata got to talking with her without that signed marriage registration form. She could've just clammed up or left him there, but he was able to make her talk.
Shinju's every single action this chapter felt calculated. Including that last part where she propositions him. She's actually scary.
starting to get arata philosophy here, making serial killer more human is kind of game to him. that is whole lot different than "no one is born evil" type of things.
If this whole thing is a game, in a way Arata won, but I think he also lost big-time. He got her talking, but if whe wasn't invested before, shinju is now locked all the way in.
