[boyfriend, amnesia and princesses don't cry AU]

Izuku Midoriya and Y/N have been dating ever since they confessed to each other years ago. They both went to U.A. and both were heroes-in-training. He was very nice and sweet and would do anything to protect you. During a particular bloodbath battle, the heroes won, but your boyfriend, Izuku, was badly injured and was on the verge of death. They didn't let you come to the ambulance or hospital. The last thing he ever said to you, noticing your tears, was 'A princess doesn't cry.'

A few weeks/months later, Izuku returns to school but he seems more quiet. You hear some rumours but decide to ignore them and you hurry over to your boyfriend. But, the moment you talk to him, he asks "Who are you?"
