Urban white-collar Lin Yuanyuan goes from hunter to believer. She fell in love with rough security guard Shen Shuai at first sight, and originally wanted to start a short-distance romance that followed "adult rules." However, when she tried to pull away, she discovered that Shen Shuai's affection and paranoia were far beyond her imagination. At the same time, the seemingly glamorous relationship between best friend Zhang Xiaoyu and elite Chen Wei reveals another complexity in urban emotional relationships. Two pairs of CPs and two love models interweave a modern urban emotional picture about desire, sincerity, growth and choice.
