One day, I met a little boy Ken on the street. What I like, it sticks perfectly to Spank and I can't leave. He says he's sad that his mom went back to his parents' house. A babysman who is disqualified for everyone except for the punk, and I can't refuse to refuse and accept the punk. Spank protects Ken-chan who does unexpected things one after another. It's hard, but it's comfortable to be relied on. On the other hand, Aiko, who watches over her, is also complicated by being shown the baby's loveliness and difficulty. " I wonder if I'll be able to hold a baby like that now..."
