"I must thank you. I wasn't there, but if you hadn't helped the Crown Prince, he might not have been able to use his healing power again. Now, if you want anything, just tell me and I'll grant it." 

He tilted his head slightly, waiting impatiently for me to make a request.

"I-I..." 

*Just then, someone knocked on the large door and it suddenly opened. This door only responded to the royal family and opened automatically with their blood flow. No one else could open it, especially these types of doors found in the empire’s organized rooms, which held a lot of information. When the door opened, I was once again faced with the boy. Maybe I had been asleep for three or four days, and now, after all this time, I missed him.*

"Father"

"Good, you came too." 

The boy glanced at me out of the corner of his eye and then turned back to the man. He acted as if he wanted to ignore me. Why was he behaving this way?

"I just asked this girl what I should give her to thank her. How can you help her as well?"

"…"

I didn't know what to say. I felt the atmosphere in the room couldn't get any worse. Were this father and son really like the rumors said? In the past, everyone knew that the Crown Prince hated his father, but no one knew why.

"Stay here."

"What?"

When the boy spoke, I was shocked. He wanted me to stay in the palace?

"You want this girl to stay here, Jamie?"

"Yes, and I hope she wants to live here too."

"…"

They both stared at me as if waiting for the final answer that would settle everything.

"But... I can't stay in the palace... I mean, I'm..."

"You're not going to say you're just an ordinary angel, are you?" 

"Jesa, I realized you have two combined cores, and when Jamie was close to you, you fainted, so you reacted strongly to Jamie's power."

He chuckled, and his eyes shone even brighter than a few seconds ago as if he was enjoying this moment.

"A demonic angel must stay in the palace."

"…"

Jamie lowered his head and said the words as if he was uncomfortable. It seemed like he didn’t want to say them or maybe didn’t want to force me to stay.

"But... here, and me?"

"Don't worry. Your mother was a princess, and you have royal blood in your veins. No one has the right to mistreat a royal princess, even from the demon family."

"…"

He seemed very sure of this, so he must intend to do something.

"So, will you accept living here?"

"Whatever Your Highness says."

"Good, then you can live in the palace comfortably and behave like a princess, treating this place as your own home, Jesa."

"Thank you, Your Highness."

He nodded and turned to Jamie, gesturing to him.

"Jesa, come with me. I'll show you around."

Energy Core: Instead of a heart, angels/demons have an energy core. For angels, it shines and is golden depending on their power, while for demons, it is black or sometimes red depending on how sinister and powerful they are. Sometimes the term "death" is used, but it's not possible for them to die easily. They only die if a special sword or immense power destroys or empties their core, and they might be granted the ability to be reborn after 500 years, depending on their luck, they might be reborn in their own bodies.

Demonic Angel: The core of a demonic angel is a combination of black, red, white, and gold, and they can use any specific part of it whenever they want.

Knights of the Demonic Angel: The demonic angel must be at the center of a star, with six knights forming the six points to surround and control it with their power. Sometimes the demonic angel might go out of control due to its immense power and go insane, so the knights must restrain it with divine chains.
