Adeline didn't expect she would transmigrate into the trashy novel she read years ago. The plot was so cliched that she couldn't bring herself to finish it. Years later, she found that very book on her bed, the page was open to the villainess' execution and before she knew it she found herself in the very novel she hated. 
The evil villainess who couldn't stand her two childhood friends become completely enamoured by the female lead, she decided to take care of the matter herself and thus became the public enemy.
She now became the villainess of the story!
"I do not accept this!" Adeline yelled at the top of her lungs. "I will change the plot."
The Crown Prince she rejected won't leave her alone. The cold Northern Duke clung to her and wouldn't let go. The Arch Mage wants to abandon his duties and serve as her personal knight, and the Head Priest is obsessed with her!
The Male leads she wished to avoid won't leave her alone!

Obsessive male lead- check. Funny but strong female lead- check. Amazing family- check. Annoying Goddess- also check.

The Male Lead isn't Following the Script!

Harnessing the powers of the monsters that plagued them?

Adeline frowned, a sense of foreboding settling over her. "What do you mean?"

Dimitri's grip on her hand tightened slightly. "He began experimenting," he said, his voice low. "On humans."

Adeline froze, her breath catching in her throat. "What?"

Dimitri's expression darkened. "You know how young mages come to face the trial, right? The ones who fail… They're usually killed by the monsters before they can reach the Mage Tower. At least, that's what everyone believes. But my master… He was collecting them. The injured ones, the ones who barely survived… He would take them and use them for his experiments."

Adeline's eyes narrowed, she knew where this was going. She was not stupid. The implication was clear... But still, she had to ask. "What kind of experiments?" She said with an uneasy feeling.

Dimitri hesitated for a moment before answering. "He… He was fusing them with the monsters."
