you were laying in bed, on your back just scrolling through your Instagram feed. When Katsuki came into your dorm, this was a regular thing so you didn't do anything. He came over to your bed and laid down in between your cleavage, wrapping his arms around your back and making himself comfortable, he didn't say anything

you blushed because usually he laid on your stomach or next to you, but you shook it off and continued scrolling using one hand, the other hand was in his hair
