"Senpai, please play me!”

Isamu Asano spent his days alone in a corner of Sakuragawa High, absorbed in online mahjong. Then one day, his highly social underclassman Sakura Kamiya invites him to join the school’s mahjong club and he finds himself trying real, face-to-face mahjong for the first time.

Confident in his skills, Asano expects to dominate. But whenever Kamiya-san sits in the kamicha seat, his specialty, calling tiles, stops working, and he can’t seem to get the upper hand at all.

Is it the psychological tension unique to live play? Or is she reading his thoughts?

As he wrestles with those questions, he gradually realizes that Kamiya’s presence is growing larger in his heartin this mahjong romantic comedy.
