What is the story and ending of the movie "Going Out"?

Their spouses are lovers, and they were both unconscious in another car accident. In the process of taking care of their lover, they gradually came into contact with and discovered this secret, perhaps out of punishment for their spouse's betrayal or because of their long-lasting relationship. They crossed the final bottom line, but they seemed to be at a loss, panic and anxiety about the unexpected events. In the later days, they occasionally went out on a date, during which Xu Ying's husband Hao Jing died in a coma, but Xiuzhen woke up and Renxiu could not ignore his crying wife. Looking at Renxiu, Xu Ying realized that it was time to return to her original life. So, they dated for the last time and ended their intimate relationship. But it is obvious that this is spilled water and an arrow. The distance of space can't stop the feelings of two people who have been generating, but they can only endure suffering and hide each other deeply in their hearts. In the last scene of the film, Renxiu is debugging the concert lights when it suddenly snows (this is the origin of April snow! ) He held out his hand and looked into the distance! There seems to be another scene where I received a text message from Xu Ying, but I don't remember it. I'm not sure. )
