Uuugh!!! Worst ending ever!!! Why get therapy and then go back to your abuser? That's not how rape works. I got it, stockholm syndrome and whatnot, but geeeeez. He's gotten therapy, he should know better. Hanabusa should just keep interfering and get Haruki back, cause that demon brother needs to spend the rest of his life alone and regretting his actions. It'd be best if the little fucker went to prison.
