The extra who sacrifices herself for the beloved female lead. Princess Shuelina who is tossed aside by her biologically related father and older brother. Now I’m the main character of this odd situation. In regards to hope, I’m still neglected at this orphanage. Just as I was going to run away before the imperial family found me–

“Did you hear? The House of Grand Duke Vailot came to sponsor an orphan.”

To find a way to live, I threw myself at the villain's family, the Grand Duke’s, and-

“You can do whatever you want. I, as the Grand Duke, will protect you.”

“You’re not an orphan. You’re my younger sister.”

Why do they love me?

Just as I made up my mind to live well since I'd already become a lady of the House of Grand Duke Vailot...

"I have searched for you for a long time, my child."

This time my biologically related father, the Emperor loves me. Why are you acting like this? I said, I don't need you guys who wouldn't have listened to what Shuelina had to say. I refuse to accept your love!
