You suffered from the illness known as insomnia..

You would stay up all night and go about your day exhausted, and you despised that so much; you wanted that to stop. You could never sleep at night because of that.

Megumi Fushiguro is the only one who could help you with this. Your older brothers best friend..Yuji itadori, your brother.

It all happened a few months ago during a sleepover; you and him shared a bed with a few other people, and he slept next to you. The first time you fell asleep was in his arms.

You never mentioned that to him, but ever since, your view of him has changed. But he's oblivious.
