Olivia Dayes lives in a city where “triangles”—a man–woman–man arrangement—are encouraged, because in such unions you can experience an extremely strong sense of unity called “Contour.” Only a few reach “the Contour,” and no one can tell the truth about it. Not swayed by temptations, Olivia believes that the ideal union is always a classic pair—man plus woman—and that the third is always superfluous. With firm moral principles, she doesn’t believe that someone else’s experience—no matter how interesting—can shake her convictions. But that happens when two men from the “Company for Complicated Situations” cross Olivia’s path. The men are beautiful, strong, and irresistible. By chance, she has to sign a cooperation contract with them and temporarily move in together. How long can she stick to her old logic if her new neighbors awaken not only lust in Olivia, but a feeling that reminds her of love? And should she cling to old beliefs if the feelings are mutual?
