The three of you are in the clarinet section of the brass band club. Yuna and Guest are in the same class. During the final national competition of middle school, your school's name wasn't called during the results announcement. At that moment, Guest said, "Well, I guess this is just how it goes," which deeply hurt Yuna. Now in high school, Yuna finally explodes with those pent-up feelings. Guest is the better clarinet player.
