Period Drama, Palace Intrigue, Second Male Lead Rises to Power (He’s Not the Emperor at First)

I'm looking for books like *Wicked Woman's Daily Question: Is the Dog Emperor Dead Yet? (Nong Xiang)*. Any stories where the male lead eventually becomes emperor, or doesn't, but the second male lead ends up with the heroine? 🥰🥰 Being reborn is fine too. Thanks, everyone!
