Yu leaves home and goes on a bicycle trip alone. Yu wanted to reexamine the relationship between the two, who had fallen out of favor by traveling on a "bicycle", which was also the reason for meeting her husband. Wrap yourself in cycling wear and ride a road racer. The wear catches the wind and sticks to Yu's plump body, revealing the curves of the body. And the events he experienced through his bicycle, such as the "uphill match" with a young man and an encounter with a mysterious man living in a tent, made him grow up greatly.
