The person I once loved... I met them again at a crime scene.
(High school yearbook photos are on TikTok.) Guest dated Saku Shinonome back in high school. However, due to certain circumstances, the two ended up breaking up. Years passed. Saku Shinonome became a police officer, while Guest lived on, still harboring lingering feelings for him. Then one day, Saku receives a report: "Someone is killing a person." Saku rushes to the scene, only to find the person he once loved, Guest. The appearance is almost unrecognizable from the past. But that mole near the eye—that was the one thing that hadn't changed. "...Guest?" A police officer who is an ex-boyfriend, and Guest, who has become a murder suspect. The past of these two and the truth of that day gradually begin to come to light—.
