What kind of love story does this movie tell?

A * * * has three stories. The first kind: after marriage, their passion disappears. As most people expect, their love and marriage will last for a long time. Zheng Yang and Wen Hui are together. The enviable fairy-tale love in the past has turned into pots and pans and endless quarrels with the passage of time. Although the two people in reality live a good life, time has already polished the old passion beyond recognition. As a company director, Zheng Yang's unbearable work completely drained his energy. He ran away from home for a day intentionally or unintentionally, and slept in the hotel for two days and one night before his fatigue eased slightly. Strangely, Wen Hui, as a full-time wife, didn't look for him, and the hotel was opposite his house, so they staged the back window incident. On one side, Wen Hui is at home, and on the other side, Zheng Yang is at the hotel. As time went on, Zheng Yang gradually discovered Wen Hui's mysterious identity and strange feelings. I began to get to know this woman and our feelings for each other again ... the second kind: reunion for many years, which continued the separation of 12 years ago, but I still failed to meet again. It was not until a class reunion that they met again surrounded by everyone. Of course, it was an orgy. Alcohol awakened all the rashness and impulsiveness of the youth who had been sleeping for many years, and everyone forced Zheng Yang and Wenhui to "renew their frontier". At this time, Zheng Yang is an auto mechanic, and is preparing for a divorce. Wen Hui just got divorced, took her children and made a living by selling mobile phones in the electric city. At this time, their life and love are down and out, which also makes this night a rare beauty. That night, they tried their best to find their lost appearance, revisited those old streets, climbed over the old iron gate, and returned to the bar called "Tree" ... However, everything could not be redeemed, and what was lost was lost until Wen Hui said to Zheng Yang, "Come home with me" ... The third kind: single, and he met her with a bad marriage. Bordeaux, France, single from 12. That's Wen Hui's voice, crossing mountains and rivers. It turns out that she is married and going through a marriage crisis. Occasionally, she dialed the phone-the number that has been waiting there and will be dialed one day. When Zheng Yang arrived, she witnessed the heroine of love that she could not copy, and suffered the betrayal of marriage and the collapse of her mother. He participated in the great changes of her family, silently accompanied her, and watched her despair of love a little, as if the breath of life had slipped away from her body. He successfully stopped this self-destruction and regained the burning of Wenhui. At this time, Wen Hui's husband came back and Zheng Yang left quietly. Until now, Wen Hui knew that he had never changed over the years. ...
