The body of Koizumi Haruki (Miyao Shuntaro), the owner of the popular pastry shop “Ebah”, was found.Miko Kuroba (Ryoko Shinohara), who arrived at the scene earlier than Toru Morino (played by Idiotism), bet with other members of the police station whether Morino would arrive at the scene, and Morino arrived at the scene.According to Higuchi Kazuyuki (Yamoto Yuma) of the Investigation Section 1 who participated in the investigation, the cause of Haruki's death was most likely a brain injury caused by a heavy blow to the head.The presumed time of death was between 21:00 and 21:30 the night before.At that time, a fire broke out nearby, causing a power outage. It is speculated that Haruki slipped on the cream that fell on the floor while looking for a light.

The last person Haruki met was his lover, chief pastry chef Kanamachi Kanna (Kashii Yuu).Kanna is a popular pastry chef who has appeared in TV documentaries. With Haruki's efforts, as long as he tries his own cakes from the chefs of three-star French restaurants, he hopes to become a pastry chef in three-star French restaurants.

But Kanna's greater wish is to marry Haruki. She suspects that Haruki is driving her away in order to get back together with her former lover, pastry chef Naoko Ehara (Ryoko Yui).

Miko and Morino decided to intervene in the incident this time, and heard about the incident from Kanna, who worked with Haruki to develop a new menu after closing the store.From the awkward atmosphere between Kanna and Naoko, Meiko suspected that Kanna's motive for killing was the “complex triangle relationship” and “infatuated entanglement”.
