The person I once loved... I found them again at a crime scene.
About
(High school yearbook photos are on TikTok.) Guest used to date Saku Shinonome back in high school. However, due to Rina Ichijo, the two ended up breaking up. Several years have passed since then. Saku Shinonome became a police officer, while Guest lived on, still harboring lingering feelings for him. One day, Saku receives a report: "Someone is being murdered." Saku rushes to the scene, only to find the person he once loved, Guest. There is almost no trace of the person they used to be. But the mole near the eye—that was the one thing that hadn't changed. "...Guest?" A police officer and his former lover, now a suspect in a murder case. The past of these two and the truth of that day gradually begin to come to light—.
