Takei plays the role of an university student studying in the department of engineering who comes from a rich family while Ayano plays an assistant professor. The two of them work together to solve various mysteries. Although the atmosphere of the story is on the thrilling and tense side, the mood on the set is joyous. Ayano revealed that they recently had a fun fair where there was a Ayano shop set up to sell all sorts of things including snacks, shampoo and underwear. Takei complained jokingly that Ayano even took her photos to the shop to sell without telling her.
