What is this chinese historical drama

I've been looking for an specific chines drama my sister told me. She forgot the title. The ml is an unfavored son and married the fl. The scene she remembers is the fl is pregnant and about togive birth but was schemed against and the baby died, while at the same time the ml is drank and was about to go to her but was assisted to another courtyard. My sister can't remember if the ml slept with the other woman or if the woman pretended he did.

After times pass by the fl was sentenced to live on a faraway property of the ml but there she met other concubines. She said the fl is quite cold hearted with the ml and a schemer. After getting sentence to live faraway, she schemed her way back, though my sister said the ml really love her 😂(which 8s funny for me)

Does someone know this chinese historical drama? I'm not sure if this was released on year 2023 or 2024. The ml looks a little older(not that handsome😅)
