Tenohira Size

Uozumi Aiko, an employee at Rainwater bookstore, is 29 years old and single. Despite her family pressuring her to "get married soon", she lives life at her own pace. But one day, Aiko is frightened by a young man staring at her at work. However, it turns out that he's her cousin! Moreover, they're going to live together?! This is the story of a clumsy woman and a clumsy man living together.

Life does not always go as planned. Noriko fell in love, got engaged, and imagined a bright future. Instead, her fiancé fell in love with her older sister, Eiko. Noriko refused to let go, and they ended up getting married despite this significant problem. Some years of marriage and two children later, Noriko became a single mother. She returned to her family home, with her daughters Eri and Madoka. Her life continued, alongside Eiko (who ended up never marrying or leaving home), and their now elderly mother. Years later, Eri and Madoka are entering the time of life where they have their own problems with love. This manga follows the lives of this house of women.

The Onishi family doesn’t have a father anymore. They don’t have much money. They don’t even have a shower. Tenohira Size presents eight stories of a mother and her three children’s day-to-day lives in the aftermath of divorce.
