Kobayashi, who had the fate of being a "good-looking guy but a virgin" due to an anaconda-class big cock, was sympathized by Yamamoto who met at the university and was invited to fulfill his virginity. Kobayashi, who graduated from university in the third year of dating due to twists and turns, decided to return to his parents' house in Mie and help the sake brewery. Yamamoto, on the other hand, decides to train in Nara, the birthplace of sake, in order to become a full-fledged brewer and contribute to Kobayashi Sake Brewery. After a year of long-distance relationship, Yamamoto, who has successfully completed his training, can get a job at Kobayashi Sake Brewery, and the two will be able to stay close at any time.
