Izuku snuggling anything/anyone that's next to him whenever he's asleep (which is why he has a couple of fluffy pillows on his bed) although the thing is that class A has no idea because he's been very careful to rush towards his room whenever he feels sleepy. He doesn't mind to snuggle with any of his friends, but he doesn't want to make them uncomfortable (he's really shy about it).
However, Katsuki knows this because Izuku used to do the same when they were kids and now that his relationship with the nerd is leaning towards a more friendly territory, he's made sure to constantly sit next to him whenever the whole class or maybe just Katsuki and Izuku's friends are hanging out together.
He's been very patient... Waiting for the perfect opportunity when finally, it happens.
They come back from the gym showers after a very intense training session, but decide to hang out for a while in the common room, Izuku is ready to go to his dorm because he's exhausted, but Uraraka and Ashido convince him to stay with them at least for a little bit.
Katsuki, as usual, has secured his spot next to Izuku, much to Todoroki's and Uraraka's irritation and as they all start talking about each others' quirks, Katsuki notices that Izuku's eyes are closing on their own.
He stops himself from fist pumping the air when he feels soft curls over his shoulder and doesn't dare to breathe for a couple of seconds until he hears Midoriya sigh and feels him snuggling closer until his face is in the curve of his neck.
Katsuki is blushing to the tip of his ears, but he doesn't care if everyone is looking because the nerd is getting even closer and puts his arms around him.
When he's sure Izuku is completely asleep, Katsuki puts his arms around him as well.
Class A has stopped talking and they're staring with shock, jealousy and confusion as Katsuki starts running his fingers through Izuku's hair gently until his nerd sighs, pleased.
"Maybe we should take him to–"
"If you wake him up, Half and Half, I'll blast your head off," Katsuki snarls, he somehow manages to make it sound threatening even though he's whispering.
The truth is that he doesn't want anyone to ruin this for him.
Todoroki glares back at him (Katsuki knows the bastard is not afraid of him) but he nods anyway, probably because he doesn't want to startle Izuku.
"Does he always do that?"
"Ever since we were kids. Turns into a little shit who's constantly craving for snuggles, and it's even worse during winter," Katsuki answers Yaoyorozu's question without realizing he has a fond grin on his face.
"That's why you're always sitting next to him?" Kirishima asks suddenly.
That's when Katsuki realizes his mistake, he gave them too much information. He doesn't answer the question because there's no need to, they all know.
"Which means he'll snuggle anyone sitting near him..." Todoroki mumbles, eyes on Izuku, ignoring the way Katsuki is baring his teeth at him.
The next week is a nightmare; Katsuki has to make sure Izuku goes back to his own dorm early because everyone is trying to get him to sleep next to them.
Izuku has no idea what's going on.
