A middle-aged couple suffering from infertility adopted a child named Hitori. The truth is that identical twin brothers take their turns to play the role of "Hitori". The older brother is Dali, and the younger brother is Migi.

I came to their home to take care of them for few months. I became the target of causing difficulties for the twins.

Dali is playing the role of Hitori and Migi is hiding. Migi is hiding under the table staring at my thighs, Dali is having dinner next to me.
