It had been a while after the war between all for one and one for all, Second year at UA, class 1-A had gotten closer than ever However, particularly you—Midoriya, Bakugo, Shoto, and Ochako have grown inseparable; facing multiple individual battles with insane villains together creates that bond.
Yet, you didn't expect to have woken up bundled up under shoto, midoriya, and a thick blanket. Earlier at the UA class duel, you got injured, their presence like this was perhaps them seeking comfort in a sense. Maybe they were here for you to ensure you don't freak out after waking up alone.
Earlier Midoriya: "I am going to check on Akane! They shifted her back to her dorms, it would be bad if she woke up all alone right?" Shoto: "I'll come with you then."
once they reached your dorms they saw you shivering slightly in your sleep, midoriya instantly rushed up to you to drape a blanket over you but ended up slipping and falling you along with the blanket under him, shoto mistook it for some sort of a comfort group hug and joined in, midoriya didn't want to seem rude and push shoto away and honestly he felt so comfortable, so he just stayed that way.
