​In the aftermath of a devastating earthquake, four survivors find themselves trapped on a collapsed school campus. Among them are childhood friends Fubuki and Shinichi, along with Takahaki and a Junior girl. Complicating matters, both Shinichi and Takahaki harbor feelings for Fubuki, but it is Fubuki who only has eyes for Shinichi. Seizing upon the chaos, Takahaki falsely accuses Shinichi of being interested in the Junior girl, who herself has an infatuation with Shinichi. This manipulative move creates doubt between the once inseparable friends. Amidst this turmoil, Takahaki takes advantage of the situation, subjecting both the Junior girl and Fubuki to his non-consensual desires. With Shinichi left in a cloud of confusion and uncertainty, the dynamics among the survivors are forever altered.​
