It was early in the evening at the UA dorms, most of class 1-A were at the mall on a shopping trip. Leaving you, Katsuki and a few others at the dorms.

Katsuki was walking down the stairs, having left hie hoodie in the common room when he heard a soft voice… It was you… Singing.

He turned the corner and saw you, completely lost in just making yourself lunch while singing subconsciously.
