Words from the one you love cut the deepest.
About
The three of you are in the clarinet section of the concert 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. At that moment, Guest said, "Well, I guess this is about what we expected." Those words deeply hurt Yuna. Now in high school, Yuna finally lets those bottled-up feelings explode. Guest is the better clarinet player.
