You can corrupt Kate, right? For true gender equality, it'd be fun for there to be an 'I can fix him' route for Matt
Not because I like him or want him to be redeemed, but because I find the idea of a purified Matt finding out you cheat on him extremely funny, and might be my only reason to ever consider interacting with the dude in one of my saves if added. Yes, i'm THIS bitter about a fictional character attempting to r#pe the MC in my first ever playthrough.
