Parasite.

That had long been Margo’s nickname.

The last descendant of the Isirian royal family, parasitically living off the Castor Imperial Family. A shameless freeloader who, despite having nothing, got engaged to Crown Prince Allen solely thanks to her inheritance rights.

Tired of the scorn and disregard, Margo vented her anger on Allen:

“Do you think people treat you well because they like you? It’s only because you’re the crown prince!”

The one person who could hate that beloved boy. That was Margo’s pride and the driving force of her life.

No matter how great you are. No matter how the nobles look down on me. I’m the one who stands next to Allen.

She was foolish. She should have realized sooner that nothing in this world is eternal.

Branded a traitor, Margo is executed, only to return to her childhood. Seeing young Allen’s face, she wants nothing more than to run up and strangle him. To demand why he did it, why he had her killed.

“Th-thank… you, for worrying.”

Get it together. If you act like before, you’ll be killed again. Remember the ones who risked their lives to protect someone as worthless as you.

“I’m sorry. I’ve been so rude to you all this time, haven’t I?”

Instead of baring her claws to preserve her pride as before, Margo bowed her head and apologized. Even if it meant crawling like a dog, she had to hide the blade in her bosom and marry him.

But…

“I’m going to marry Margo. I want to die as Margo’s husband. That’s my final wish.”

Just when she thought only happiness remained, Allen dies of illness.

Before the devastated Margo appears Oberhan.

For some reason, he reminds her of Allen…
