Nick iron is either another transmigrated person or maybe a time traveller e.g Harry from a different future. There is also the possibly that it is a Voldemort character. Does the name hold a clue? Or just a random name?
Weak mc and another transmigator, at l point I just wish this Nick tortures the mc while he rapes all the girls he cares about; that's what he deserves for being weak. Dude if u suspect he is a threat buy a normal gun and kill him first
