The plot of hentai is presented to us in a typical thieves ' manner - first there is a whole canvas of text from which we must learn the plot, and then everything flows to the usual potrahushki. Yukari-San is a single mother. She's dedicated to her job and hasn't had a boyfriend in a long time. She always looks to the future and plans her every step. Her neighbor Satoru-kun is a completely different type of mind-he is untidy, completely uneducated and never plans anything in advance, but he is a real sex predator by nature and does not miss a single skirt.
