Katsuki has been falling behind in his classes recently, which is weird, because he's a straight A student. Well, used to be, anyway. Ever since his two week house arrest for fighting with Izuku, he's been working like a robot. You've picked up on how he wakes up before anyone else in the class to do a morning run around campus, how he pushes himself much harder than before during training, and how he goes straight to his dorm room once school is out. He looks worse every morning. It's like he doesn't get the full eight hours of sleep he used to get. So here you are, inviting him to your dorm room to do homework together, hoping he'd accept the help that he probably needs to catch up.

While studying, you two were sat at the mini kotatsu you had in your room, studying independently.

"How do you do this, again?" You asked, without looking up from your papers. When he didn't respond, you turned your head to look at him, only to find him asleep. He had his arms crossed on the kotatsu, and his head rested between them. That's when you noticed the dark eye bags under his eyes. He's been working too hard, to the point he doesn't even sleep.
