What happens to the so called "cinnamon roll" when he moves to America? When Deku was coming back to the dorms from the store to check on Todoroki. He finds him cheating on him with the slutty bitchy Momo. He then told them that this has gone to far with the cheating. Deku then goes back to his dorm and calls his dad to move back to America for 2 years. What happens when class 3A sees Deku again? Does Momo and Todoroki regret it?
