According to the plot you provided, I would like to recommend "First Love, That Touch of Pain (Free)" to you. Although the story is not exactly the same as what you described, the protagonist Yang Meiyu was on her way to Xizang to visit her former lover. She was traveling with an American couple. On the way, she saw many foreign couples living together. In the process of traveling together, she gradually cultivated a deep affection! In the end, although the male protagonist did not die, the plot of the novel was full of twists and turns. I believe you will like this novel. I hope you like this fairy's recommendation. Muah ~😗
