Maybe it was an evil joke of fate.
They are destined to perish for each other.
However, they all made the mistake of being too rational, analyzing their own feelings and meeting the future too rationally.
Although separation was not the final outcome, it was the only choice they could make at that time.
See you again many years later,
He has a wife, and even though it is the product of a business marriage, he is still very good to her. However, he occasionally sees his wife as another very ordinary person.
She is still single. Although she has had several relationships, her boyfriend told her when they broke up: There is someone in your heart. You always compare me with him subconsciously. Although you never say it, I can feel it.
The author's artificial result is that their fates intersected seven years later.
