Through middle school, best friends Miho Shirokawa and Miho Yoshii bowled together.

Yoshii's high school curling team has decided to try to make it into the next olympic winter games! Shirokawa thinks about quitting bowling and joining a curling team as well, but unfortunately, there isn't one at her high school.

Before she realizes what's happening, Shirokawa's has become the founding leader of her school's Curling Club! How will she face all the difficulties of starting up the team, when she only has the vaguest idea of what the sport of curling is even about?!
