Sirens: a name derived from an ancient creature, used to describe those who could charm, lure, control, and heal others by singing.

Subjected to live the life of a siren, Aria had experienced, seen, and heard many horrific things. Broken beyond repair, Aria resigned herself to death, when suddenly…

The Grand Duke, Lloyd Cardence Valentine, arrived and whispered, “Should I kill everyone here?”

“If you need me, just call me. Your song will always reach me, wherever you are.”

In the end, Aria called the devil, bringing death to all those present, along with herself.

“Let’s fall down to hell together.”

And with that, Aria breathed her last and died… only to return to her 10-year-old self.

Now that she had a second chance at her life, Aria was determined to change her fate, as well as the cruel fate of her saviour, Grand Duke Valentine.

And so… Aria proposed to him with a marriage contract.

She sold her soul to the devil and vowed to protect him.

The young duke took the contract from her hand.

“So, where should I stamp the seal?”

“You said you’d divorce me within 10 years.”

The grown-up villain leaned in, hovering his head before he kissed her tenderly over her crown.

“Now that we’re adults, we should sign another contract.”

She is the slow-witted idiot of the Prime Minister’s Residence. Everyone bullies her. He is the most respected and unfeeling Prince, with frightening ability and absolute envy! Together, they are conferred an imperial edict of marriage.

She acts stupid and tries to decline in every way possible while he despotically escorts her into the wedding…… everyone ridicules the match, but no one knows that the “idiot” has transformed from a loser into a talent.

After the marriage, when they encounter the Empress Dowager examining the room, they act in concert with each other and pretend to be two mandarin ducks deeply in love. Afterwards, she laughs, “The performance has ended. Your highness, please return.”

He laughs softly, “Since you’ve got onto this Prince’s bed, don’t even think of getting off.”
