Boku wa Imouto ni Koi wo Suru

Yori's attitude has changed. Once, he and his twin sister, Iku, were inseparable as children. But lately, Yori has been different—eager to be apart from Iku. Iku worries that he hates her, but the truth is far more scandalous. Now, Yori would risk losing everything to have his little sister. Iku loves her big brother so much that she would never risk losing him, so she'll do whatever it takes to keep them together. But Yori doesn't want her in that way—as a sister dedicated to her twin. Can Iku ever love Yori not as a brother but as a man? "Brotherly Love" won the Shogakukan Manga Award in the shoujo manga category in 2008. The series was published in Spanish by Editorial Ivrea, in French by Soleil, and was adapted into a live-action movie in 2007.
