What is the photographer's letter in Love during Cholera?

Take the last sentence of this book as the title, because I don't know what to take as the theme. I bought this book for a while, and finally I finished it intermittently. It's a little messy, but in general it's about two loves of a woman. A secular marriage love, a spiritual love that spans 50 years with Paula model. It is also mixed with all kinds of love that Ariza attached to the process of love in order to fulfill his dream in this life: poverty, nobility, vulgarity, rudeness, debauchery and shyness. I have to say that this is a good book, and every detail and every stage of the characters' emotions are worth thinking about. Probably because youth doesn't understand love, it took some book reviews to understand it slowly. Some people say that Marquez wrote loneliness to the extreme when he wrote One Hundred Years of Solitude, and love to the extreme when he wrote Hoai. Two people can't get married at the age of twenty because they are too young; After all kinds of twists and turns in life, at the age of eighty, they finally came together. Maybe it's because you're old that you fall in love. I think of a very popular story in Weibo. Probably one person waited for another person to wait until he was 80 years old and finally got together. We are all willing to believe and admire such stories, because such stories can make us feel that love is beautiful. I love someone all my life, but I prefer to believe that the company of life is the happiest thing compared with such a fairy tale. Firmana is the embodiment of idealism. She has a perfect husband to accompany her through most of her life, and in her twilight years, she made her first love a positive result. In the end, this love living on the boat decided to sink into the sea until the end of my life.
