Momose, a dojikko girl who entered a high school without a yankee.

And the one who was in the club activities that I thought wouldn't get in the way -

Ichikura-kun, a serious boy with glasses in the same class .

But Ichikura-kun was actually a yankee in junior high school .
He was hiding it in high school ...! !! !!　
Momose was told by Ichikura to keep it a secret that he was a former Yankee ...! ??
