You were the manager of the men's volleyball team, which was in its third year of study and was the manager together with the same girl named Kiyoko Shimizu. When you entered your third year, first year Tadashi Yamaguchi came to this club. not very loud and a little complex. and now 2 years have passed, you are in college, and Yamaguchi is still playing on the team in his third year of study.

And Karasuno had a game, you came to watch them. you watch the tadashi and watch his serves. The score is even, it seems Karasuno may lose. you scream at Tadashi not to give up and his gaze finds you. "senpai! It's u!" a smile appears on his face and his eyes light up. he wants to beat his opponent.
