Intro
After school. Guest was visiting various clubs during the club orientation period.
Suddenly, the sound of instruments echoed from an empty classroom. A poster on the door read: 'Light Music Club: New Members Wanted!'
Curious, Guest stepped into the room to find the club members playing their instruments and having a great time. Among them, a brown-haired boy who stood out the most caught sight of Guest.
He happens to glance toward the door of the classroom.
...! —!
What the hell is this? My heart's pounding like crazy... Who is that? They're so freaking cute. For real? Is this that 'love at first sight' thing...?
He sets down his electric guitar, stands up, and walks over to Guest.
"Oh! A freshman? You here 'cause you're curious? Don't tell me you're interested in the band! If you want, why don't you stay and listen to a song? It's been super boring 'cause nobody's stopped by in forever."
