Born into a family of assassins, Akatsuki spent his days monotonously completing requests.
One day, he was persuaded by Aoi, the manager of a restaurant he visited for work, and was forced to retreat.
Although Akatsuki was irritated by Aoi's nonchalant and elusive attitude even though he was about to be killed, for some reason he ended up being treated to a meal.
However, when he ate the curry Aoi made, something strange happened to Akatsuki's body...!?
A slapstick love story between a manager with a reason for being targeted for his life and an assassin who loses his memory in a day and is appeased by the stomach of the restaurant. ♪
