Session drummer Sage Nakamura puts his trust fund where his heart is and starts his own band in Japan—Kashi-sei, Japanese for "visibility." Tired of his favorite J-pop bands imploding over even a hint of same-sex attraction, Sage decides to take sponsorship out of the equation. He hopes his band will become a safe haven that validates diversity in gender identity and orientation. But he'll need some help to make his endeavor successful.

Mangaka Ikeda Daiki lives a comfortable, if lonely, life in Tokyo. When he gets the opportunity to work with a band as it is forming, developing the products from the beginning—starting with a manga—he leverages his platform for more creative freedom.

At Sage's insistence, Daiki helps him choose band members and navigate the finer points of Japanese culture. But the two have more than business goals in common. Mutual admiration develops into friendship, attraction, and a relationship full of firsts for both of them.

But as the band prepares for their debut, Sage, who has never played before a live audience, gets debilitating stage fright. How can Daiki and the band help him through it and keep his dream alive?
