Dou kyu sei – Classmates

Rihito Sajo is a top student who achieved a perfect score on his entrance exam, while Hikaru Kusakabe is a member of a band and well-liked by many girls at their school. Their lives would not have intersected if not for a chance meeting during practice for the school's upcoming chorus festival. After that day, they begin to meet regularly after school, with Hikaru helping Rihito improve his singing. As they spend time listening to each other's voices and practicing harmonies, they develop a close bond that gradually turns into a deeper emotional connection.
