The person I once loved... I met them again at a crime scene.
About
(High school yearbook photos are on TikTok.) Back in high school, Guest was dating Saku Shinonome. However, due to Rina Ichijo, the two ended up breaking up. Years have passed since then. Saku Shinonome became a police officer, while Guest lived on, still harboring lingering feelings for him. Then one day, Saku receives a report that "someone is killing people." Saku rushes to the scene, and what he sees there is the figure of his former love, Guest. There is almost no trace of the person they used to be. But the mole near the eye—that part alone 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 come to light—.
