In the snowy mountains, Fujiki collapses and is saved by Kagawa, a coffee shop owner. Despite Mikako's offer to assist him in finding the culprit, Fujiki declines. The next day, something catches Fujiki's attention in the shop.
Fujiki suspects Kagawa is unwell after detecting an odd taste in Kagawa's dishes and noting behavioral changes, only to find Kagawa has a taste disorder from an auditory nerve tumor. Determined to cook for his daughter's wedding, Kagawa decides to receive help from Fujiki.
While being pressed by Takuro for a murder admission, Fujiki escapes. During the struggle, Takuro grabs Fujiki's phone. At the same time, Takuro, pretending to trust Fujiki's innocence, approaches Mikako.
