Take an example of him vs the autist from My new life. In my new life he genuinely helps people not expecting anything. He does some questionable shit, but on the whole, seems to genuinely want to help a lot of people.Basically that's the MC in a nutshell.
Aside from his sister. It seems like he wants to fuck her because some other guy does. That shit is creepy. It's like me getting angry at my brother in law for having a kid with my sister.
