An unidentified woman (Ogo Jujuka) died leaving behind a Shiba Inu, which was actually the woman's relic.After forensic autopsy, the woman's cause of death was acute aortic rupture.He died while walking his dog. No foul play was discovered, but witnesses reported that a figure fled the scene when the body was discovered.

Since the woman wears a ring on her left ring finger, she may be married or in a relationship.Sakura (Koshiba Fuka) and Makoto (Oshima Yuko) want to find clues as soon as possible so that the remains can be returned to their families.They found the words “MAKOTO” on the Shiba Inu's collar. It seems that the Shiba Inu's name is “MAKOTO”.Sakura whispered: “No wonder it doesn't look very flexible.”Zhenze squinted his eyes and asked: “What do you mean?”At this time, Horiguchi (Shigeyuki Totsugi), who was checking SNS, discovered an account using MAKOTO's photo as the avatar.This was most likely the account of the deceased or his family, but during the investigation, things took an unexpected turn.

The woman's name is “Chiaji”, and she uses a dating app to meet multiple men.What is puzzling is that men have different impressions of Chia.In front of one man, she is a quiet museum artist; in front of another man, she is a cheerful and talkative company employee; in front of yet another man, she is a passionate yoga instructor.Their personalities, careers, and hobbies are all different, and no one knows Chiaji's real name or birthplace.Is she... a marriage fraudster?

The incident seems to have a certain flavor. If Chiaji's family members cannot be found like this, Shiba Inu MAKOTO will be sent to a health center, and in the worst case, he may be euthanized.In order to find out his identity, Sakura Kazuma took MAKOTO around.

The unidentified body turned out to be a marriage fraudster?The thoughts entrusted to her beloved dog... Where does she really want to return to?
