The story is set in Hiroshima Prefecture's Onomichi City, where a high school student Nashiko Jippensha was kicked out of her house. Without a place to play with her friends, she learns that the mahjong parlor that her father used to run is now vacant. She fixes the mahjong parlor and turns it into a place where she and her friends can have fun, cook, have tea, and sometimes play mahjong.
