《L禮香的真實》是《M為了心愛的人》的衍生劇，講述了從禮香的小學到高中時期的故事，以及對所愛之人抱有異常的執着的理由。

A woman’s dead body is found in an apartment in Kokubunji, Tokyo. The decayed body seems like a half year has passed since its death and it is damaged by domestic cats that ate the body. The woman's death is thought to be a "lonely death" (someone died naturally without anyone noticing for a long period of time). Detective Ayano has doubts about that conclusion. The cats seemed like they were not house trained, which is odd for domestic cats. Detective Ayano wonders whether the cats were really owned by the dead woman. Detective Ayano then finds Suzuki Yoko’s bankbook in an empty fishbowl. It seems like the dead woman is 36-year-old Yoko.
