PPAS-005 Nana Usami: Daughter’s Relationship with Mom’s New Husband. The woman I’m dating has an only daughter, Nana-chan. I felt it was my duty to support them, and the three of us became a family. Of course I love the woman who became my wife, but when I think that her daughter Nana is mine, she gets so excited that she can’t sleep at night. I took a bath with Nana-chan again today and cleaned various places. Nana-chan, let’s study with Papa again today.
