- Description from novelbuddy

Athena Grant,a human,dies in a car accident and becomes Eira Liora,an elf. Transported to the barren and cursed island of Luinmir, a once-thriving land now abandoned.A year ago,their King announced that the island,Luinmir would no longer be under the empire's control. It was well known that the land was barren and poverty stricken...She was abandoned both by her Kingdom and her Father.She wakes up one day with a system.“So what if they were abandoned and deemed cursed,she would show them all the highest peak of knowledge and development. The island's core is broken...fine,she'll get it replaced but this time,the island would become hers to keep,she would make sure of that.”

She became the young mistress of the most powerful family in City T by marrying the young master in place of her sister.

He was cold to her on their first nuptial night. "Just because you played some tricks to get yourself married here, you still mean nothing to me!"

However, she was calm and heartless. "Young Master Mu, don't think too highly of yourself. I despise all that is you — your money and your very being!"

After the wedding, Young Master Mu lived lavishly by spending money like flowing during the day while working his nights away busily. "You said you despised me earlier. Well, which part of me do you despise exactly, hmm?"

Luo Chenxi could not bear the harassment any longer so she tossed out the divorce papers in rage. "I can't live like this much longer..."

It was in the middle of the night that the woman who would be the Duchess came to see me.

She said my father and mother died, and my kind uncle became king.

She said it’s not worth it for me, the crown prince, to be living in hiding, too.

“A while ago, Your Highness had been hiding from me. With all due respect, is that for the sake of survival? Just because your parents died doesn’t mean you have no reason to survive. Actually, that fact alone made it all the more reason why you should live. If you die now…”

If I died now?

When I asked her while looking at her eyes, the woman eventually brought out the harsh truth with empathetic eyes.

“It’s like a dog’s death.”

“That’s rude….”

It’s been a long time since I said that. In a short while, he has been treated as a madman and beaten to death just by saying similar things. She loosened her arms that held me and I suddenly stiffened up due to it. Because I thought she might have loosened her arm to hit me. But she didn’t.

She knelt down with one knee in front of me, just like a knight.

“Hastred’s Sarian raised her salutations. May you accept it gladly.”

My first knight is beautiful and kind.

“Are you on my side?”

“Yes, Your Highness.”

It was all a lie.
