Liang Liang met Miao Miao in the middle of the road, while she was escaping from a male friend. She just got into his car and asked him to drive her away. Liang was a good-hearted man and thought she was in some kind of trouble, so helped without asking why. They parted ways after that. But fate would let them meet again, in the course of work. How they fell in love was not clearly shown. The plot really started when they moved into a flat together.

The movie title already hinted that the couple would eventually breakup. But I had thought it would be due to miscommunications, insecurity and jealousy issues. Unfortunately no. Although it was not stated in the movie, I suspect Miao had OCD. At the start, when Liang was still staying alone, his flat was very messy. But when they moved in together, the flat was always clean and neat. And the way Miao rearranged his cigarette butts into a neat row, and obsessively cleaned the house when they quarreled, all these hint at OCD. OCD with anxiety management issues. Hence she had problem trusting Liang, and to get a sense of security, she would go to extreme measures to track Liang's movements.

Even if Liang had fewer ex-girlfriends, or had given truthful answers to her questions, all these really did not matter. She had OCD and would be a controlling girlfriend. It was only a matter of how bad the controlling would be. If he could have been more honest with her, maybe the controlling behavior wouldn't have gotten so bad.

Art direction, script and acting are good. But what is the theme of this movie? This is really unclear.... Is it about the regular issues that would breakup a relationship? Not exactly. Is it about how to love someone with OCD? Liang never made efforts to understand Miao's issues.

I would have really like this movie if Miao didn't get so extreme towards the end.
