Asuka Sumi, who works from home, bumps into his next-door neighbor, college student Rentaro Taniguchi, outside their apartment building one day. Asuka has a bit of a sweet tooth, and, wouldn't you know it, Rentaro works part-time at a cake shop. As Rentaro starts bringing Asuka cakes from work every day despite his glaring lack of exercise, he proposes a rather... unorthodox way for Asuka to get some exercise and satisfy his desire for cake at the same time.

Laughs galore in this romantic comedy BL between a promiscuous younger stud with an especially rigorous exercise routine and his cake-loving slob of a neighbor.
