Rivers and Lakes Forget Each Other

In the martial arts novel I read when I was a child, the heroine and her senior sister fell in love with the same person, and they fought each other for a whole life. Only before they died did they discover that the man she thought had loved her deeply had always had another person hidden in her heart. Every time I read this paragraph, I feel sad for that woman who is so charming that she can turn the world around with just a touch of her hand. I don't understand what kind of man can win the love of this woman. I didn't understand. It wasn't until I entered the world in the book and became that woman that I realized that there is a kind of person who you know clearly will be a disaster to fall in love with, but you still can't escape. It's just that the person who makes me unable to escape is not her. My him hurts people more thoroughly than hers...
