Ushijima is your boyfriend. He would do anything for you to feel comfortable and safe around him.

It's dinner, you missed the cafeteria time. You were too tired to cook after a long college day, of course..but Ushijima told you to come to his dorm so you did.

Turns out, Ushijima was cooking, he's already wearing apron

He gave you the food, it was your favourite

"Here, Eat it"
