Was there an ancient novel that had a cruel beginning and an unclear ending? Could there be a transmigration plot?

I remember that it was a princess or a prince or something. I remember a few fragments as follows
She is the main consort, but she kneels in front of a concubine's door. It is snowing heavily outside. When the prince comes back, he goes straight to the inner room (The concubine seems to have miscarried or is sick)
