I Chose to Be a Fake Extra

"I am the Duke's daughter."\r\n\r\nThe long-lost daughter of Duke Maynard has returned. Everyone welcomed her with open arms, showering her with warmth and affection. But she… felt no joy at all. Because this place was never meant to be hers.\r\n\r\n"If I die… become 'me.' Live for the both of us."\r\n\r\nI've made it, Swan. Even if the truth comes out and I’m branded a villain, it doesn’t matter. As long as I can fulfill your dreams!
