Alice (Koo Hye Sun) has always been rejected by every guy she confessed her feelings to. One day, she returns a lost cell phone to a strange salesman then jokes about wanting a boyfriend as reward. To show his gratitude to her, the salesman gives his business card and tells her to go to his company's website, Kronos Heaven.
At the Darling Store section of the site, Alice is surprised to see that she could create her own customized absolutely perfect lover. The next day, she is shocked when her new lover, in a form of a robot, arrives.
Just after exactly 48 hours has passed, the salesman appears at her door to inform her that she did not return the product within the 48-hour trial period. Therefore, Alice must pay for the robot, Henry (Jiro Wang).
Alice now works hard to pay for Henry. But what if Alice slowly starts to fall for her "Absolute Boyfriend"? Can she stop herself from loving a robot before it's too late?
