Helena Parizu lives in a world on the brink of war. To help her country achieve peace, Helena—who has the ability to construct unusual mathematical sequences—does secret message relays between rebel camps. Like any woman, she wants happiness, tenderness, and a long-term relationship, but in these uneasy days dating sites are full of men who want only one thing: “let’s do it quickly.” Tired and disappointed with this approach, Helena impulsively makes a move that’s not like her: on the advice of a friend, she buys a robot. The benefits are obvious: not a spy, doesn’t interfere with work, no scandals, doesn’t demand attention, knows how to cook, clean, give useful advice, be a friend—and even hug when necessary. An excellent investment. If only the model she bought were a real robot and not a living man from another world sent to help prevent the war. His mission is simple: pretend to be a robot, infiltrate her home, swap three “cipher messages,” and then return. The mission is doable if she keeps her composure, doesn’t slip up, and doesn’t allow feelings to appear. After all, you don’t fall in love with the “object.” Or do you?
