She fell in love with the prince, but before they could get married, he died in battle.
She died in love by crashing into the coffin, was seriously injured and lost her memory, and mistakenly thought that his seventh brother was her husband.
On the pillow for three years, he kept his brother's last wish, wearing the title of substitute, loving her but not daring to touch her at all.
It wasn't until her memory came back and she left with red eyes that she realized that she had fallen in love with someone she shouldn't have loved.
"Yunjue, are you a substitute or yourself?"
"I am your husband, always have been."
Purpose: To tell the story of a misplaced relationship, in which the male and female protagonists struggle with ethical taboos, love and guilt, and finally break down the lies and barriers, face the true heart, and achieve self-reconciliation.
