ah sure the new guy, I'm talking about the MC lol. Well about the childhood friend yeah.... it was weird what happens later.... but again we are not even sure at this point if it will go into this direction because little by little they are changing here.This new guy (who appears on this chapter) DID very explicitly try to grape his sister in the WN. And ends up with her moving away from her parents house because of it.
It was the childhood friend that didn't. Which kinda messes up the story because he ended up redeeming himself. Kinda difficult with a grape attempt and all.
