I will enter the imperial harem with my beautiful older brother.

Iri lost both parents in childhood and has been living under the care of her older brother, who possesses rare and exceptional beauty. On the day Iri graduates from school, her brother suddenly announces that he will enter the imperial harem. Thus begins the leisurely harem life of Iri, her beautiful brother, and their carefree childhood friend—a life full of bewilderment. Iri meets kind people, worries about her strained relationship with her brother, makes efforts to get along with him, feels down and happy, and experiences romance. While there are subtle reverse harem elements, the heroine remains devoted to one person. This is primarily a story about mending the complicated relationship with her brother.
