This book tells the story of married pair Chieko and Sakujan and their path to "living together in life". Chieko and Sakujan have been married for 11 years without having children; they live together as just the two of them. Chieko works as a clerk, and Sakujan owns a shoe mending business.

Their everyday routine includes working, going to the grocery store, eating together, and having talks. Even though they occasionally disagree, they are sensible enough to guard their relationship's happiness.

This is the physical copy of the Chi-e-ko's Small Happiness manga.
