A quiet history teacher and a bright math teacher have a secret love for each other while getting along day and night, but they are limited by reality. In the end, one person goes to a secular marriage, and the other person can only stare at the happiness that has nothing to do with her in the dark, and whisper: "Happiness is good."
Intention: When destiny is destined to be missed, the deepest tenderness and ultimate dignity that a person can show is not possession, but silent protection and sincere fulfillment.
