From MangaHelpers:

Ichino Bungo presents us with a compilation of short stories, where love and sex goes beyond what we might consider as normal. Sex-service offered to the wrong client? “Casual” sex between good friends? Rape because of a conspiracy? In this world, all kinds of incidents, from the strange to the weird, occur without our notice. This series displays a small fraction of these strange relationships, that people embrace, the world has to offer. Could you be the next person to be involved in such an “embraced” relationship?
