Summary
The day Izuku Midoriya met his idol, All Might, should have been the best of his life. Instead, it became the day everything changed—and the day he forgot.
After a head injury during the Sludge Villain attack, Izuku develops anterograde amnesia. Each night, his memories reset. Each morning, he wakes up believing it’s the day before he became a hero. He forgets One for All. He forgets UA. He forgets the people fighting beside him.
But lately, it’s not just the present slipping away. There are names in his phone he doesn’t recognize. A girl who says she’s his twin sister. People who already know him before he’s ever met them. What if he’s not just forgetting the present … but pieces of the past too?
AU: Izuku suffers from short-term memory loss and anterograde amnesia. His family is growing. The world keeps moving. But Izuku can’t hold onto time.
Inspired by the film 50 First Dates.
