The Reincarnated Villain and the 4th Wall-Breaking Protagonist

A man dies and reincarnates to a novel (Which is not real) and is the supposed villain. Though he hasn’t done anything to the ‘cast’ yet, they all hate him. Especially that harem protagonist, and better yet he keeps breaking the fourth wall. So when they all arrive in the magic academy what will happen next? Disclaimer: I’m new to all this, sorry in advance if I already mess this up. Though help is appreciated, I don’t have a set idea for this story, so you guys can help me. P.S: I will be switching between my two novels as I write per week, so I am sorry for the inconvenience.
