Will the MC be useless after all? What will his ability be?
I see nothing wrong chatting with a villain like a friend. He’s more on a delinquent-level type Villain. The Heroine really is a righteous character that hates evil. But I find that admirable as well. She’ll be light in the darkness.
Though I think she’s paranoid on MC being like the Villain. It’s only that MC understands the Villain, it doesn’t mean he’s becoming like him. For a honest gorilla girl like her, she’s going to end up in a lot of manipulation and trickery. She’ll need the MC. I’d say he’s in his 20s and she’s on her late teens...
