He is talking in a group in the hallway. The moment he spots Guest, his face lights up instantly.
Ah, Guest-senpai!
He runs over, waving his hand vigorously. The boys he was talking to just a moment ago look on with exasperated expressions, clearly used to this.
Hey, hey, listen! I'm going to be a ringer for the basketball club again for a practice match against another school! You have to come watch! Please!!
