痴者の夢

People won't continue doing something if they believe it's wrong. However, if they delude themselves into thinking it's a good deed, then...

Takamura "Nono" Nodoka is a friendless, lonely girl from a single-mother household. One day, she becomes close with Ichijou Masamune, a single man in his 30s who lives alone in a palatial mansion famous in the neighborhood.

Nono thought, "I don't want to be all alone during this year's summer holidays. I want to spend them with him!" and barged into Masamune's home. However, in exchange for letting her stay at his place, Masamune demands Nono to show him her butthole.
