(Salted Rose) After I Gave up My Status as a Co-Wife, They Regretted It

The Female Protagonist Wakes up and Leaves, and the Male Protagonist Is Cremated.

I have watched the heroine play the hero before, and they are childhood sweethearts. When I was a child, the hero had anxiety disorder, and then the heroine went to work as a servant, and the hero got rid of it. Then the heroine left, and the hero went crazy. Although the plot is very cliché, I wanted to watch it, but I can't find it.
