Lisa can finally celebrate after finalizing her divorce from her terrible husband. That is, until she receives news that her ex-husband has been murdered and she is the suspect. The poisonous herbs that killed him were sold at her shop, and they found her scarf tied around his neck. To make matters worse, the detective who's interrogating her is none other than her ex-boyfriend, Nash, whom she once considered marrying. To figure out who's framing her and who really killed her ex-husband, she decides to work with Nash for the first time in four years. Source: Harlequin

My job is mostly at night, which means I'm constantly fighting sleepiness every day. The girlfriend waving at me from the sidelines of a buffet, the email that said *"I'll break all your joints,"* the old friend I was with while "waiting to be punched" by a coworker... We all eventually forget everything, good and bad. That's why I'm writing about the things I didn't want to forget. (Source: Kodansha, translated) *Notes: \- Chapters 2 to 6 were split into two parts in the original serialization and later combined in the volume release. \- Includes one extra chapter.*
