Izuku Midoriya:

You two were over at his house when it happened. You both were in his room with the door wide open, since his mother didn't like the thought of two teenagers alone with the door closed. But he didn't mind, still watching the show you both were watching.

Soon enough, he fell asleep with your head on his shoulder. Inku walked in with a plate of snacks but decided to gently lay them beside you both and silently turn off the light. Walking out, hiding her tears that her son was growing up.

Katsuki Bakugo:

You were hanging out with the Bakusquad in the mall when it happened. You have been telling him earlier that you were sleepy but he wasn't listening. Until he felt your head fall on his shoulder. He tried waking you up but then just gave up., closing his eyes and leaning on you.

"Take a picture, I'll fucking kill all of you." Bakugo said as he heard the others giggling.
"Oh come on, Bakugo. It's cute!" Sero laughed as Mina pulled out her phone to snap a few pictures. Bakugo opneed his eyes and gave them all a glare. But he didn't want to move to wake you. So he stayed still.

Tenya iida:

You both were staying after school hours to tally up the winners from the cooking competition. But as Tenya was doing the finishing tallies. He felt you slump on his shoulder, looking over he saw that you had fallen asleep on him. A small blush appearing on his face.

Once he finished up the work, he very carefully got up and lifted you into his arms. Grabbing your bag and slinging it over his shoulder as he began to walk you home. Making sure you weren't going to wake up. Getting to your house, he used a spare key you gave him and tucked you in.

Denki Kaminari:

It was during lunch. Apparently you stayed up most of the night studying for a test Mr. Aizawa had that morning. And while he talked and ate, you had slumped over his shoulder and began to rest. He didn't mind this, he could eat your food anyway.

But he made sure to wake you up once he knew class was going to start soon. You told him off about eating your food but he promised to buy you something after school was over. So, once the day was over. He bought you the food he took.

Eijirou Kirishima:

You both were cuddling while watching Bakugo and Denki cook in the dorms kitchen. Bakugo had said he was going to cook something. And somehow he was now preparing a meal for the whole class. He was pretty ticked about that.

When you fell asleep on his shoulder, he only pulled you closer and left a small kiss on your forehead. Watching Bakugo yell at Denki on how he was cutting the vegetables wrong. Laughing a little once the yellow haired male got hit with a cabbage.

Mezou Shouji:

You had come to Shouji when you had gotten done with your hero training. You had taken a shower so you were already sweat free. So he didn't mind all that much. But he tensed a little once he felt your body go limp.

Looking over, you had fallen asleep on his shoulder. Thank god it wasn't anything else. But he let you sleep for about ten minutes until you had to head back to class 1-b.

Tetsutetsu:

You both were in the dorms. You both were watching the tv about some drama show with Kendo. But you both weren't really interested in the show. Tetsutetsu was playing on a DS while you tiredly stared at the screen.

He glanced down at you once he felt the weight on him. He gives a small smile before shifting himself where your head laid on his lap. Leaning back and playing more.
Kendo awed a bit. Quickly slapping Monoma's neck before he said anything.
