It's been a month since I lived with my nephew Ataru. My aunt, Akari, is conscious of being a man, and casually invites her to make me feel like that. Ataru, who has a strong sense of self-control, refuses to follow Akari no matter what. She can't help but feel so frustrated that she has to console herself every day. One day, Akari, who was taking care of Ataru, who was bedridden after hurting his back at work, suddenly played with his meat stick as a good thing because he couldn't move because of his injury.
