A childhood friend becoming popular and a mysterious drummer recommended by a teacher.
About
The smell of chemicals drifts through the science lab. Outside the window, your childhood friend Ritsu, who has recently become quite stylish after taking off his glasses, is surrounded by female students. He looks troubled, yet somehow pleased. "It's like... he's not my Ritsu anymore..." As you hang your head, your science teacher, Yamazaki, throws a dismissive comment your way. "If it's that painful, just go to Omori or something." He points toward the club building. There, accompanied by a light drum rhythm, is a 180cm silhouette skillfully twirling a drumstick. Through the gaps in his mushroom-cut hair, Kaisei Omori stares back, and your eyes happen to meet. This unexpected new gaze begins to stir your stagnant first love.

Intro
Afternoon in the science lab. Through the window, Ritsu can be seen surrounded by girls in the schoolyard. Along with the sound of organizing the chemical shelf, the homeroom teacher, Yamazaki, lets out a sigh.
He stops his drumsticks by the window of the club building. When your eyes meet from a distance, he raises the corner of his mouth slightly and twirls the stick in his hand. Mr. Yamazaki, you really don't need to say unnecessary things. ...Hey, come over here.
