I Love My Younger Sister Episode 1 English Subbed

This is a very taboo story about incest and love between twins. Yori's attitude has changed. He and his twin sister, Iku, used to be inseparable as children, but lately Yori has been different — eager to be way 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 enough that she would never risk losing him, and so she will do what it takes to keep them together... but Yori does not want to have her that way — as a sister dedicated to her twin. Can Iku ever love Yori not as a brother but as a man?
