Kaoru Hanabishi, a university student, is the eldest son of Yūji Hanabishi, the head of the Hanabishi Zaibatsu, and was set to take over the zaibatsu after his father retired. His mother, Kumi Honjō, and his father never married, making life difficult for both him and his mother. Kaoru’s father died when he was five years old. Since then, Yūji’s father, Gen’ichiro Hanabishi, took Kaoru under his wing and began educating him for the eventual succession. Yet Kaoru never felt at home in the Hanabishi family and went into self-imposed exile after his mother’s death. Day by day he felt alone, thinking that he was living life with no reason pushing him on.
There was, however, a person who loved Kaoru so much that she had to do whatever was necessary to be with him.
Her name is Aoi Sakuraba. Aoi is the only daughter of the owner of the Sakuraba Dry Goods Store (later renamed to Sakuraba Department Store). Kaoru’s family and Aoi’s family had expected for Kaoru to marry Aoi, but after Kaoru walked out, the marriage was canceled. Both families had a friendly relationship and Aoi had been in love with Kaoru from the start, which Kaoru was unaware of. The Sakuraba family had already been searching for someone suitable, but Aoi was unwilling to marry someone else and walked out, chasing Kaoru.
Both were freed from their families’ affairs, but did not know how to make their living. Miyabi Kagurazaki, who had been looking out for Aoi, offered the two a way for the time being. Aoi and Miyabi would live together in a grand western style summer house owned by the Sakuraba family and Kaoru would live in a house for servants next to it. This would prevent a scandal, much like the one that had made Kaoru’s life difficult, as the two would be living separately. But soon, Kaoru’s friends, who just happen to be attractive females, took residence in the servants’ house, and it quickly became a dormitory and Aoi became landlady of the dormitory.
Kaoru eventually comes to terms with his painful past by confronting the Hanabishis. Later, Kaoru’s half brother attempts to gain control of the Hanabishi Zaibatsu by marrying Aoi, but Kaoru meets her father who accepts Aoi’s relationship with him, foiling his half-brother’s plan.
