I Don’t Like You At All, Big Brother!!

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!!

High school junior Nao Takanashi is deeply in love with her older brother, Shuusuke. Her intense brother complex drives her to extreme measures, such as secretly entering his room to dispose of any material she deems a threat to her goal. However, her world is shaken when she discovers a childhood photo album that mysteriously lacks any pictures of her, leading to a revelation that challenges the very foundation of her feelings.

This discovery coincides with Nao facing fierce competition for Shuusuke's affection. Iroha, his attractive childhood friend, and the diligent class president Mayuka both enter the fray, creating a chaotic love triangle. As Nao navigates this new reality and rivalry, she must confront the complexities of her emotions and find a way to make Shuusuke see her not as a sister, but as a woman.
