Hen Imouto × Youthful
編妹×ユースフル
A high school boy lives with his younger stepsister, who is cheerful and openly affectionate. She constantly invades his personal space and makes playful advances, leaving him flustered and unable to concentrate. Despite his attempts to maintain a proper sibling distance, her youthful energy and lack of boundaries create a tense and awkward atmosphere at home.
As her behavior becomes increasingly bold, their relationship teeters on the edge of propriety. The boy struggles with his own growing feelings, caught between societal norms and the undeniable attraction he feels toward his stepsister. The line between familial affection and forbidden desire blurs, leading to a situation that neither of them can easily control.
