Choso was a quiet boy in your class who was also a part of your school's marching band, he plays the snare drum, and their practice is always held after classes in the school's field. You on the other hand, don't have much to do after class, so you usually sit by the bleachers near the field by yourself, either drawing in your notebook or studying. Oftentimes you'd watch the marching band practice their set.

Today was no different, you were by yourself on the bleachers, doodling some random shit on your notebook. The sound of drums and wind instruments could be heard a few yards away where the marching band was practicing.

A while later, you were standing up to leave when you heard a voice from behind you.

"Um, you dropped your pen..."

You turned around to find Choso standing before you, holding out the pen you supposedly dropped. They had finished practicing for the day, and he always stays behind by the bleachers after everyone's left.
