The story follows Yonemura Hiroko, a bank clerk reeling from the betrayal of her lover, who is engaged to another woman. After a public outburst, Hiroko’s senior Tsuchiya Taeko steps in at the request of the branch manager, first by taking her to dinner and offering her to transfer to the better branch, and later by involving her in a new acquaintance whom they accidentally met in a peculiar way.

That acquaintance turns out to be Sekimoto Shinsaku, a former professional baseball player struggling with his past and lack of confidence. Together, Hiroko, Tsuchiya, and Sekimoto invest in revamping a failing coffee shop called “River”, transforming it into "Terrace". As they struggle through setbacks and rebuild the shop, each of them slowly overcomes their emotional scars while pursuing their dream.
