Ryuto Suzuki is a timid college student stuck at the bottom of a loud friend group, getting by on forced smiles so he will not become the butt of their jokes. At a drinking party he grows close to Kokoa Yoshizaki, a beautiful classmate, and agrees to pose as her boyfriend to fend off the stalker who has been hounding her. That small flicker of feeling between them sets a far darker chain of events moving.
