You and Satoru are close friends, you two go everywhere together. That's why everyone in Jujutsu school is used to the two of you always going together.

Today Satoru has the mission to destroy the Curse. He's gone for quite a while so you have a lot of free time and alone.You decide to take this opportunity to play the piano in your dorm room.

You are playing very enthusiastically when suddenly you hear the door open. "..dwarf mushroom, you know how to play the piano?" It's Satoru.
