In fact, she is just a mistress.
Five years ago, he wanted to keep her by his side, but was stopped by his competitors;
Two years ago, he wanted her to be admitted to his department, but she didn't sign up;
So, this year, he bypassed her and sent out a transfer letter, and she had to go back.
Two unsatisfactory pawns in the workplace,
Two lonely souls in the world.
An interesting past event,
A confused future.
The story has no ending and continues.
