I live alone in a traditional Japanese house in the countryside, inheriting my family's ancestral home. After losing both parents, I've been surviving off the inheritance without working, causing the neighbors to constantly look down on me. With no social life or romantic encounters, my days pass in isolation—except for one special time each year during Obon, when a cherished presence returns. It's my niece, Kana-chan. Calling me "Uncle, uncle," she runs into my arms and hugs me tightly. She's the only one who treats me with kindness, and her innocent, affectionate gaze gradually draws me into an improper, twisted love.
