Nice to Meet You, My Best Friend

University student Shotaro Tokito shares an apartment with his childhood friend, Rin Kazama. During their youth, the two were inseparable, doing everything together. Shotaro was fiercely protective of Rin, who constantly followed him around like a shadow. However, after moving in together, Rin’s demeanor shifted dramatically. He grew distant and cold, frequently bringing women home and creating an undeniable rift between them that left Shotaro struggling to understand what went wrong. The fragile tension shatters when Rin brings a woman into their shared home without permission, sparking a heated argument. During the confrontation, Rin strikes his head and loses all memory of their strained relationship. To support his recovery, they agree to continue living together as though nothing has changed. Surprisingly, Rin reverts to his former self, clinging to Shotaro with the same intense attachment he displayed in childhood. Yet beneath this familiar devotion, something feels different. As Rin’s affectionate behavior intensifies, Shotaro begins to suspect that his best friend’s sudden return to form may be driven by hidden motives.
