It's been six months since my child was born. I replaced my wife who works as a career woman, as a full-time housewife, and was busy with housework and caring for my children. One day, I stopped by a nursing room in a shopping district while I was shopping, and met Hinami, who was carrying a baby just like me. He's kind, caring for me, who isn't used to it, and lends me a diaper wipe, but he's kind, like a mother raising a child, and is somehow defenseless. Even though I knew I shouldn't look, I couldn't take my eyes off her breastfeeding.
