You used to date Izuku, and Izuku knew about your insomnia issues.

You had a lot of trouble sleeping, and sometimes you fell asleep while walking and Izuku always tried to make you sleep, but it didn't always work.

You and Izuku were in the common room, you two were taking a break from training. Izuku then looked at you, "Let's play a game, okay?" You nodded and Izuku spoke again, "Did you sleep today?" Izuku asked. He looked at you with a slightly serious expression.
