52-year-old Tsukumo Sakura owns Tsukumodo, a secondhand bookstore which stands alone in the Ota district of Tokyo. People of all generations visit this shop which revolves around manga. At the back of the bookstore is a room called Tamariba. It is a place where people with nowhere to go seemingly gather out of nowhere. And Sakura serves oyakodon without poking and prying into their backgrounds or circumstances. The dish is free for anyone and also delicious. It fills stomachs and also seems to warm hearts. With their hunger satisfied, the people “with nowhere to go” slowly start to talk to Sakura about themselves and she listens to them. Sometimes she encourages them with a smile. At other times, she cries with them. She loves to say “It’s all right to cry when you want to. The teardrops that fall will simply burst into flowers of happiness.” Meanwhile, Sakura herself has to face a tragic past. An incident 16 years ago spurred her to make oyakodon for free. One day, a teenage girl Ninomiya Azami visits Tsukumodo and time starts to rewind
