In the legendary era of bands made up of beautiful girls, forming a band is the same as getting married, and playing a live show is the same as throwing a party. So what does it mean when a band breaks up? Against this backdrop, Asai Yuto, a boy, gets a call from his childhood friend Nagasaki Soyo, whose band has just broken up.
"Please, let me forget everything."
"???"
After careful consideration, Yuto declares, "I can't let her be a widow again."
As they form a band and play live shows together, a beautiful white-haired girl with different-colored eyes appears and tugs at Yuto's sleeve.
"Live show, together?"
Soyo cries out, "Is this what cheating looks like?"
Togawa Rāna shakes her head. "I'm not here to break you two up. I'm here to join you."
