There is actually nothing wrong with a man and a woman falling in love and living a life-long relationship. But just when you don't want to love, someone falls in love with you; when you turn around and want to learn to love, the person you want to love has already disappeared in the vast sea of people.
Maybe life will be fine without love. Many years later, when I look back on the inadvertent publicity I had when I was young, it has become a calm and clear thing. In fact, there is nothing wrong with this kind of memory. It is not enough happiness but more than regret.
