After the soul-searching trip to Hokkaido, Xiaoxiao (Shu Qi) has gotten over her bitter affair with Mr. Fang, somewhat disillusioned with romantic relationships. But one man still gives her mixed feelings: Qin Fen (Ge You) is a considerate and funny guy for sure, yet he's too moody and childish to be the man she wants to walk down the aisle with. Although Xiaoxiao has tried to convince herself that Qin is her Mr. Right, she's too conscious of the difference between liking and loving. On the other hand, Qin is pretty sure he wants to end his bachelorhood with Xiaoxiao. In a bid to find out whether they really suit each other, the two rent a villa in the scenic Sanya to begin their "trial marriage"...
