东京大田区，在羽田机场附近一处可以称之为乡下的地方，有一间叫“九十九堂”的旧书店。书店以漫画为中心搜罗了各种旧书，顾客群广泛。店主九十九樱平静地过着日子。旧书店深处有一间被唤作“休息室”的房间，那里常聚集着一群不知来自何方且无处可去的人。店主阿樱不深究这些人的来历，而是 端出亲子饭款待饥肠辘辘的他们，而且亲子饭对任何人都是免费的。无处可去的人们在填饱肚子的同时，内心也得到了温暖。他们渐渐地把自己的事说给阿樱听。阿樱静静地听着，有时也会和他一起流泪。她的口头禅就是：“想哭的时候尽管哭吧。因为落下的泪珠会开出幸福之花。”来吃亲子饭的人中，有因复杂的家庭环境而烦恼的女老师，有杀过人、从少年管教所里出来后仍寻找“爱”的少年，有在公司失去地位的自闭男性。人人都有各种的故事。而阿樱自己也有必须面对的悲伤往事 。

Sakura runs a secondhand bookstore in Tokyo. Customers of various age ranges visit her secondhand bookstore. Deep inside this bookshop is a room called the “meeting place.” People who do not have a place to go, gather in the room. She gives them oyakodon for free. In the room, people talk about themselves, while Sakura listens to them. She sometimes encourages them with her smile and sometimes sheds tears with them. Azami and Rie are leading a lifestyle full of delinquent behavior. One night, after being chased by mobs, Rie points out at the bookstore, a good place to get free food.
