On the first day of the new year, Lu Yunfei sent a short message to Sophie, pouring out her thoughts and pains. Mu Beibei (Cecilia Han) finds Sophie's mobile phone in the subway, and then begins a tortuous love story with Lu Yunfei.
Mu Beibei, a tour guide, once picked up the wrong guest at the airport and met Lin Lizhong (played by Li Mingshun) from Singapore. Lin Lizhong liked Mu Beibei, but when Mu Beibei knew the true identity of Lin Lizhong's rich family, he refused him. Lin Lizhong is not discouraged. Whenever North North encounters difficulties, he is always the first to give care and help, which makes Mu Beibei very moved.
An accident, let Mu Beibei know that he loves Lu Yunfei. But this time Mubeibei met Sophie. It turns out that Sophie is seriously ill and runs away from home because she doesn't want to drag down her sister Yuri Eberwein (Luo Shanshan). North North took Sophie in, but struggled to tell Lu Yunfei the news of Sophie.
Later, Yuri Eberwein misunderstood that Lu Yunfei abandoned Sophie because she was ill, and took revenge on Lu Yunfei. She introduced Lu Yunfei to Sophie. Yun Fei didn't know that Sophie, who was about to marry herself, was accidentally found to have a hereditary mental illness, and her condition could not be controlled. In order not to bring pain to her beloved, she chose to leave without saying goodbye. In order to feel guilty and compensate Sophie, Lu Yunfei chose to spend the rest of her life with Sophie, and Mu Beibei also quit.
Beibei decided to go to Singapore with Lin Lizhong. When bidding farewell to Lu Yunfei, she sent a message to an unknown number with Sophie's mobile phone, and agreed with Lu Yunfei that if this message returned to Sophie's mobile phone two years later, it would prove that they were destined for someone.
Two years later, Mu Beibei has returned to his hometown in Xitang, China. The bell at the end of the year is getting closer and closer, and Lin Lizhong is waiting for Mubeibei and his fate. Will fate SMS return to Mubeibei's mobile phone again?
In the face of Lu Yunfei and Lin Lizhong, two men who have feelings for themselves, what choice will North North make? Everything depends on fate.
