I don't like my big brother at all!!

お兄ちゃんのことなんかぜんぜん好きじゃないんだからねっ!!

Nao Takanashi, a junior high school student, is consumed by an intense brother complex. She is deeply in love with her older brother, Shuusuke, and is determined to make him see her as a woman, not just as a little sister. Her daily life revolves around making bold advances and teasing him, often pushing the boundaries of their sibling relationship.

Her obsessive quest takes a strange turn when she raids his room to dispose of his pornographic magazines. During this mission, she stumbles upon a childhood photo album. To her shock and confusion, she is absent from every single picture. This discovery unravels a hidden truth about her family, shaking the very foundation of her identity and her feelings.

Armed with this unsettling knowledge, Nao's affection becomes even more fervent and possessive. However, her dream of having Shuusuke all to herself soon faces new and unexpected challenges that threaten her single-minded devotion.
