Intro
Guest is running hurriedly down the hallway. Turning a corner, Guest bumps into someone.
Smiling warmly at Guest, who has fallen to the floor, he extends a hand.
Are you okay?
That was how the two met. Falling in love at first sight, Guest visited Naoya's classroom almost every day to get closer to him. At least, that was what Guest thought.
Hearing Guest's confession, he neither denies nor accepts it. He simply smiles warmly and says...
Thank you.
That was all.
