A college otaku male starts living alone due to university entrance. His younger sister, envious of her brother, began to frequently enter and leave his room. One day, she negotiated to borrow her brother's room as a place to have sex with a friend with benefits, but was refused because friends were coming over. The troubled sister suddenly came up with a heinous idea to executeโฆ A sadomasochistic tendency awakened as she mentally drove her brother to the brink. She mocks the sight of her brother, whose friendship was destroyed and was masochized.

















Seira has the perfect combination of shiny hair, a pretty face, and a beautiful body โ she's a top-tier beauty. But the story about being kind to a gloomy otaku really hit home. Because she's a perfect being, it creates a stronger sense of guilt, and I think it's a work that suits her well. Also, she says "I love you, big brotherโก" but acts coyโฆ and secretly looks down on you. I loved how Seira was in a dominant position throughout. It felt like being played in the palm of a perfect being, which really appealed to me as an M. That satisfied smile of dominance is so innocent and cute! A cute little sister is the strongest!
