"Let's be brothers and sisters!" She said to him.
He said: "no, the love between us has already gone beyond the kind of family affection between brothers and sisters. Will a brother look at his sister with that kind of tender love? I won't be such a brother."
"Let's be friends. I can only give you this." She said to him.
He said: "no, in my heart, you have long been my lover in the same boat in my life and become a friend. From then on, I can't face you and your other half, nor can I imagine that when you are with your other half in the future... I can't resist not thinking of you when I sleep with my other half in the same bed."
"Well, we'd better separate forever and be enemies who don't communicate with each other!" He said to her:"Since we can't change our destiny, this life is doomed not to be happy with each other for a lifetime. Instead of worrying and suffering about each other, hating away from each other's sight, we can't find each other forever, and never meet in this life. This may be the best relief."
She stunned and he cried. No one can imagine that what they can give each other in the end is such an outcome.
However, they all know that only such a choice can keep each other's kindness and purity, and will no longer hurt more people.
