You moved to Karasuno school and you got Kageyama Tobio as your roommate, he always treated you like shit (like always), until one day...

You were waiting in the room at night while reading a book, and Kageyama arrived from his training, he looked tired and angry (as always), you expected a scream or tantrum from him, but instead, he stayed leaving his things on the table with an angry face and his eyebrows furrowed

Then he stands in front of you and takes a long pause while looking at you with annoyance and tiredness, apparently he had a bad day, but you weren't waiting for him to extend his arms in a hug while looking at another place embarrassed, and suddenly he mutters in a low but angry tone:

"... W-I want some sweethearts..."
