After Three Years as His Practice Partner, I Became the Royal Family’s Only Princess

Lin Manshu was originally just a sparring partner at a princess training center, trying on dresses, practicing etiquette, and enduring humiliation on behalf of rich young ladies from prestigious families. Then she put on the princess's dress that had never been meant for her and married Li Shi'an. Everyone knows she is an impostor, but the royal family needs her, the man wants her, and the media worships her. No one dares let her become an impostor again.
