Wen Ji (Keichiro Koyama), who works as a substitute teacher in a middle school, finally got an opportunity!There is a vacancy for an assistant professor in Professor Feng Gu's laboratory.

Wen Ji, who was full of expectations, walked to Professor Feng Gu's room, but heard the professor say that although Wen Ji should be next in order, the order is too boring%.

Wenji, who was in a state of despair, returned home. Kururi (Hiroshi Hirasawa) gave him a recipe card for Mapo Tofu he got from the supermarket. Wenji stir-fried the tofu and pork together and separated a part of it as an ingredient for tomorrow's lunch.Wen Ji felt that he seemed to have created some hope for the future, and he cheered up again, believing that good things would happen in the future.

The next morning, Wen Ji, who was called by Professor Feng Gu, was told about a surprising project involving Jiuluri. If Wen Ji could pass the test, he would be hired.
