Kimi ga Aruji de Shitsuji ga Ore de

Ren Uesugi and his sister Mihato run away from a troubled home, only to discover that freedom in the city is difficult without money or a place to stay. Their luck changes when they are hired at the Kuonji estate, where Mihato becomes a maid and Ren enters service as a butler to three wealthy sisters with very different personalities: Shinra, Miyu, and Yume.

Serving the household quickly proves to involve far more than ordinary chores. The mansion is packed with eccentric staff, demanding routines, and guests who constantly pull Ren into one problem after another. What begins as a desperate job gradually becomes a strange new home, forcing Ren to balance loyalty, family, and the increasingly complicated bonds he forms with the people around him.
