It was very interesting. At the time, I thought the ending was very sudden. Maybe after reading the novel for a long time, I got used to wanting a happy ending. Later I realized that this is actually good. Life does not have an ending for everyone and every relationship. It may feel more like a movie, a literary romance film to me than a novel.
More like an essay. I originally wanted to find a short article to increase hormones, but I was hit hard by the sourness. Sure enough, only "abnormal" love can make people painful and sinking.
