Sue and her husband, along with their daughter Yuko and Yuko's husband Tatsurou, had come to a secluded inn for a 'family trip.' Tatsurou was an excellent employee at the company run by Sue's husband and had no faults as Yuko's husband. Throughout the journey, all that came out of Sue and the others' mouths were words of praise for Tatsurou. Upon arriving at the inn, Sue immediately soaked in the hot spring, reminiscing about her husband's company and her daughter's family, savoring a happy life. But that sight was being watched by a man...!?
