Tokano Yuuka has been together with her boyfriend, Yazaki Norikazu, for a little more than a year. Unfortunately, Norikazu's job as a writer for a newspaper in a different city makes it challenging for them to frequently see each other. Nonetheless, they remain deeply in love, and everything is going well between them.
One day, Norikazu receives the opportunity to interview his old friend from high school, Saeki Keito, the lead vocalist of the Japanese band, Zero Sum Game. As a fan of the band, Yuuka accompanies Norikazu on the trip. However, things take a terrible turn when several members of the band rape Yuuka, while Keito distracts Norikazu, revealing his troubling fixation on him.
Following this traumatic event, the dynamics between the three of them become exceedingly complex. The series encompasses several standalone stories, including "Saiyaku Honey" in Volume 2, "Takaragai" in Volume 3, "Fumikiri" in Volume 4, and "Go! Go! G-bukken" in Volume 9.
