Power comes with a cost... and it was something she was willing to trade her soul for.A few nights before her wedding, Lauren sought a way to break her fourth engagement. Known for her bad reputation as the rebel princess, she was the only lady who had the guts to step foot on the Everston mansion, the house of a notorious warlord, in the middle of the night.She offered him a wicked alliance that the entire kingdom did not see coming: a marriage.A vixen pretending to be a damsel in distress and a man whose crimson eyes screaming for bloodshed. Could something blossom in this treacherous dance of lies and deception?--“Are you upset?”She eyed him sharply. “Should I be honored that I got tricked by you, milord?”He drank the remaining wine in his glass with one gulp and put it on the wooden table.He stepped in front of her. His hand was on the rail on her side while his other hand grabbed her glass and finished her wine before putting it down.The way his Adam's apple moved with his every violent gulp made her feel a tickling heat around her nape.When he brought his attention back to her, he licked his lips to wipe off the trace of wine.“How shall I make it up to you then?” he asked with his deep voice, like a seductive devil asking his victim how she would like to be killed. Dangerous yet… enthralling.

I transmigrated into a novel and became the villainess, Serina who comes from the noble Ducal Melford family.

As a well-to-do character, I tried to mind my own business, but the story had other ideas. A self-proclaimed mother brought back a boy – the duke’s heir and a genius wizard – intent on brainwashing and blackening him.

The contents of brainwashing are two things:

1. Obey our family.

2. And fall in love with Serina.

Thanks to that, the brainwashed twisted yandere is obsessed with me…

I can’t do this. I have to undo the twisted character’s brainwashing!

By the way, what’s this situation?

“Now that the brainwashing is gone, I’ll do as I please. So Serina, please, let’s do our best.”

I’ve solved his brainwashing… but why does he seem even crazier than before—

Did I make a mistake?

The world is full of mysteries. Strange, seemingly unexplainable events occur more often than we may realize. A young boy may catch an illness no doctor can explain. An office may catch fire for no apparent reason. And perhaps, someone may die a sudden and unexpected death – their bodies blighted beyond recognition.
