Centered around typical Japanese food, a solitary salesman travelling through the country for business purposes, eats at its various establishments and experiences the various delicacies of Japanese cuisine.

Kawamoto Tsugumi is a woman who is not good at interacting with people and has no friends. When she comes across an Instagram account nicknamed "White Horse", she is fascinated by how the meals are captured very attractively in the photos. The posts and captions resonate with her. Tsugumi starts to go for meals on her own by eating the same food as "White Horse". On the other hand, Shiraishi Kazuma who manages the "White Horse" account, is delighted about and eagerly anticipating the only "like" he gets for his posts from Tsugumi.

42-year-old Utsumi Takayuki works for Second Division of Hinode Advertising's Planning and Sales Department. He was transferred from the General Affairs Department one year ago, but he keeps delivering the worst sales performance. Utsumi is not eloquent, poor at dealing with things and is a pushover too. He always gets reprimanded by his boss Dozono Shoko. His only pleasure is skipping work, going to the public bath in the day on a weekday and gulping a beer down his dry throat after that. Utsumi cannot resist the temptation when he sees a public bath during working hours despite his sense of guilt. On this day too, he calls his company with the excuse that he has urgent business and walks through the door of a public bath in high spirits. When he pays the fee, takes off his suit and enters the bath, the best moment awaits him.
