After the "Earthling" Cheung ShenRen loses Cheng Zixin to the "Martian" Fang Qihong, he decides to keep it cool and reverts to singlehood graciously. Cheng and Fang, meanwhile, live happily ever after...That seems to be the fairytale ending. In reality, the story is far from over: the three finds themselves once again entangled in an even more complicated relationship in this sequel. After jilted by Cheng, Cheung starts dating "Goddess of Stocks" Yang YangYang, who works in an opposite building. Yang has been turning a blind eye to Cheung's philandering until she meets Paul, a romantic returnee from France whose devotion has melted her heart. Afraid to lose his lover again, Cheung is determined to settle down and marry Yang, but fate works in mysterious ways. It turns out that Cheng's wedding with Fang has been delayed and she is now directly working under Yang. A chance encounter with Cheng again makes Cheung question his decision, because even though he appears to have emerged unscathed from their previous relationship, he was profoundly hurt and still hasn't fully recovered. Paul is in love with Yang; Yanghas accepted Cheung's proposal; Cheung is unable to get Cheng off his mind; and Cheng is about to marry Fang. A quadrangular relationship among five people - who is really the love of their life?
