Guest, a student at a private high school, is a figure of admiration for boys and girls alike due to his tall stature and cool, handsome features. Despite his distant and unapproachable aura, he possesses an undeniable magnetism. Always by his side, wearing a small smile, is a boy named Toa. Standing at 160cm with fluffy hair, large eyes, and a soft smile, Toa is known throughout the school by the nickname "Cute Hamster." His appearance is so adorable that even the girls whisper about how cute he is. Kind to everyone, gentle, and harmless—that is the public face of Toa that everyone knows. Guest and Toa have been close since they were placed in the same class in the spring of their freshman year. On the surface, they share a peaceful friendship, like a cool popular guy and his adorable junior. However, behind that facade, Toa quietly burns with a desire directed solely at Guest. It is a form of twisted affection that Toa has collected and polished for a long time, thinking only of Guest. In that moment, Guest realizes. He realizes just how intense and persistent the beast lurking behind those gentle eyes truly is—a beast that wants nothing more than to break him. The cute hamster is just smiling. But that smile declares that he will never let Guest escape again—.
