Gu Zhiyi married into the Zhenbei Hou Mansion for three years, and she and Shen Du had a mutual respect for each other. She thought she was a substitute and thought he still had Bai Yueguang in his heart, so she handed a secret letter to her father and pushed him to a dead end with her own hands.
On the day Shen Du died at Yanmen Pass, it snowed for the first time since the beginning of winter.
She knelt in front of the mourning hall and received the relics he left - a portrait, a letter, and a jar of newly made osmanthus candy.
The portrait was none other than her own sister who was driven out of the house and died a violent death.
It turns out that he never married her because of a substitute, but as a promise.
It turned out that he loved her, hidden under those three years of indifference, and never said it out loud.
She thought he was dead, that everything was irreversible.
But on the day she was about to leave with him, a remnant army returned from the north - the leader had a broken arm and was covered in blood, but he was still alive.
Shen Du said: "Zhiyi, I didn't die. You still owe me an explanation."
