Takemoto Yuuta, Mayama Takumi, and Morita Shinobu are college students who share the small apartment. Even though they live in poverty, the three of them are able to obtain pleasure through small things in life. The story follows these characters' life stories as poor college students, as well as their love lives when a short but talented 18 year old girl called Hanamoto Hagumi appears.
Yūta Takemoto, Takumi Mayama and Shinobu Morita are three young men who live in the same apartment complex and are students at an art college in Tokyo.
One day, they are introduced to Hagumi Hanamoto, the daughter of a cousin of Shūji Hanamoto, an art professor, who has come to live with Hanamoto and has become a first year art student at the art school that everyone attends. Yuta and Shinobu both fall in love with Hagu, but Yuta hides his feelings and tries to be a friend to Hagu while Shinobu expresses his love in ways that seem only to scare Hagu, such as calling her "Mousey" and constantly photographing her. Hagu herself, though initially timid and afraid of company, gradually warms up to the three.
The group comes to include Ayumi Yamada, a master of pottery who is well known by her nickname "Tetsujin" (Iron Lady), who becomes very close to Hagu. When not at school, she helps run the family liquor store. While Ayumi is popular with many young men, she falls in love with Takumi, who does not recipocrate her feelings and considers her a very dear friend. Instead, Takumi pursues an older woman, Rika Harada, a widowed friend of Professor Hanamoto who runs an architecture studio she founded with her late husband.
The story follows these five characters in their love triangles, unrequited love, graduating from college, finding jobs, and learning more about themselves.
