After Winning Over the Capital's Young Master, I Became His Caged Canary

Transmigrate Into a Book, a Rich Man's Canary, and a Beijing Heiress's Heir

Looking for books similar to Transmigrating into the White Moonlight, I Get Spoiled by the Powerful One. I want a transmigration-into-a-book story with no System, where the heroine is a kept woman. The male lead should be powerful, like a young master from Beijing's elite circles. At first he shouldn't like the heroine, and she shouldn't have to pursue or win him over.
