I Tried to Be the Villainess, but the Tycoon Spoiled Me Rotten

A silly beauty is forced to bind herself to a “vicious supporting female character System.” In front of the unfathomably powerful crown prince of the capital’s elite, she clumsily plays the role of a “bad woman.” But the crown prince reads into everything himself, deciding her antics are just her way of showing how madly she’s in love with him. In the end, her family pays the price, while the heroine is doted on to the skies.
