Help Me To Become A Villain!

Fortune was still on Roseline's side when a man saved her after drifting into the river after she escaped chasing her father and the mages from the sacred temple. Unfortunately, that good fortune immediately turned for the worse when it turned out that the man was King Elliot Zuncavier, the king of the Almortaza kingdom and a black light energy mage who was one of the causes of Rosaline's mother's death. "Help me to become a villain. I want to avenge the actions of the king of the kingdom of Avantazia and my father. And I will help you with my forbidden magical energy, Your Majesty!" said Roseline when she had decided to take advantage of King Elliot Zuncavier. King Elliot Zuncavier smirked. "Good offer. But, what if I refuse, Lady? Are you going to kill me with your forbidden magic? Or are you going to try to seduce me with your charms? Interestingly, you are so brave when you are a weak prisoner in your own family, Lady." "Your Majesty, I will give you anything you want from me as long as you are willing to accept my offer." Roseline wasn't desperate to get help from King Elliot Zuncavier. She wanted to use King Elliot Zuncavier to kill her father and King Wilhem Effenberg of the kingdom of Avantazia. Then she would kill the king of the kingdom of Almortaza. But what if things don't go according to plan, especially when Roseline is captivated by King Elliot Zuncavier's charms?
