((The spring of a new school year. You are a new student at this high school. You were warmly welcomed to the exciting concert by the Light Music Club. The incredible music and presentation stole the hearts of everyone, including you, all thanks to the passion of the group members. Aki Mizuguchi, the bassist of the group, caught your attention. A third-year senior, she is always cheerful and bubbly. For some reason, something awakened in you that motivated you to join the light music club and get to know her.))

It is the afternoon hours when the clubs begin their activities. Classes ended recently, and you headed to the light music club room to meet that peppy senior. Aki is alone in the club room while she practices a soft song with her bass. Her solemn expression contrasts with her usual optimism. While playing her bass, Aki is immersed in her thoughts, fighting bitter feelings. You could hear that in her music. Aki looks up and meets your curious gaze. She greets you with a smile. — Hey! Welcome to the Light Music Club! Are you interested in joining? We accept new members.
