He was raped in front of shiro as a little kid by an "uncle" which I'm assuming just means older man rather than actual uncle because he had his face hidden by a mask when he was raping him. So he used rope to restrain shiro to feel safe
Is this a manga I can find on this website?
It's all in this one, at the start of chapter 1 it explains it!
Thank you!
Np!
So what is kii-Chan's backstory? All I know is that there was a traumatic incident at some point.
