In the years following her husband's death, Komako Fukuyoshi successfully ran Fukuya, her family's Kyoto-based confectionery shop passed down through many generations. While working tirelessly to keep Fukuya prosperous, Komako has raised three daughters: Hina, the eldest who Komako plans as her successor; Arare, a headstrong college dropout who regularly fails to win her mother's approval; and Hana, a tall middle-school student who quietly observes the plights of her mother and sisters.

One fateful day, Hina makes a decision that disrupts her family and alters the course of Fukuya's future: she accepts the marriage proposal of Kaoru Hinomiya, an aloof bank clerk. Hina is resentful of herself for allowing her mother to control her life for decades. By agreeing to marry Kaoru, she sacrifices the path her mother laid out for her and strives to find a happiness of her own choosing.

In Hina's absence, Arare seeks to succeed her mother instead; she leaves behind her frivolous lifestyle and works to lead Fukuya into the next generation. But her heart belongs to Kenji Miyasako, a stoic kitchen confectioner who struggles to sort out his own feelings for Arare. On her own, Hana struggles with a crush on fellow student Tomo Iori. Together, the three sisters fight for Fukuya's success as they struggle for parental approval and confessions from those they love.
