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 my daughter Nana is mine, I get so excited that I can't sleep at night. Today, I took a bath with Nana-chan and cleaned various places. Nana-chan, let's study with Papa again today.
