Shunpei is a single father struggling to care for his five-year-old son. One day, he runs into childhood buddy Sosuke, who decides to help his old friend out. Sosuke’s plan involves renting out the apartment above his rundown okonomiyaki restaurant as a share house and using the money to rebuild. When Sosuke puts out a call on social media for single parents like Shunpei, his hashtag #bemyfamily attracts the attention of Rei, a straightlaced schoolteacher, and Meiku, an ambitious singer-songwriter, each with a child of her own. But can this motley assortment of two men, two women, and three children really become a “family” just by living under the same roof?
