The days of working together made two strangers, Alan (played by Chen Bolin) and Meng Jie (played by Guo Caijie), meet and fall in love. They gradually learned to cry and laugh together and develop the same habits. It is easy to love, but it is too difficult to get along. With the hardships of life, the initial love has come to the edge of being worn out. In the days of separation, he and she have to face the loss of no one to answer and the heartache of no response. All the sweetness and beauty of the past have become loneliness that is repeatedly pulled in memory. Faced with the opportunity to meet again unexpectedly, should the two people smile and live with regret, or bravely love again? I have fulfilled you. Perhaps only I, who am the most hurt, understand that we once loved each other.
