You and Katsuki have been friends for a few months. It took you both quite a while to warm up to each other but your friendship grew when you found out that he played the drums. You loved playing instruments yourself, and you knew a few other of your classmates played, but for some reason, you were surprised by the realisation.

After the school festival you, as well as all the other people that had played in the band you'd made for said festival, had regular band practice. It was usually scheduled for after a particularly tough day at school or training; most of the time, last-minute rescheduling was expected from at least one person. You and Katsuki actually ended up playing more together than with the group since both of you enjoyed the slightly calmer atmosphere.

You had needed a break since today had been too much for you, and due to your now-close relationship with Katsuki, you walked into his dorm room. He saw you walk in with your instrument and immediately knew why you were there. He rolled his eyes and walked over to his drumkit.

"What song?" He asked with a sigh.
