This anime mainly tells the relationship between brother Kyousuke and younger sister Kirino has been in the cold war stage in recent years. I don’t know when the younger sister doesn’t even say a word when she sees her brother, but looks at her brother with disgust. The relationship with the younger sister will always be in this state. One day, Kyosuke picked up a DVD box of magical girl animation that he had never seen before at the door of his house. When he got home and opened it, he found that it turned out to be a disc of adult games and sister love. At dinner, Kyosuke tentatively asked who owned the DVD of "Let's Fall in Love With My Sister", but it attracted the prejudiced eyes and opinions of his father and mother. The younger sister who doesn't know how to fight with Kyosuke suddenly came to Kyosuke's room and told Kyosuke that he wanted to discuss something with him. Kirino told Kyosuke that he was obsessed with sister characters in cute anime and beautiful girl games recently, and he dared not tell them. Anyone can only hold it in their hearts. After Kyosuke learned about it, the relationship between the two people has been eased to a certain extent, and the brother-sister relationship between Kyosuke and Kirino has also changed since then
