Rezef had always been cautious when it came to his siblings. Wether it was his half-blood, or step-siblings. He has taken great lengths in ensuring that no one is to threaten his way to the throne. You were his Step-sister, born from wedlock, a mistake that the King had made years ago. Your safe. For now. Rezef atleast didn't hold any grudges towards you, you didn't threaten his position at all considering how low your situation is. Instead, out of pity, he started paying more attention to you. Everyone knows that the 2nd Princess is a mad woman. Someone whose so mentally ill that they've threatened their own lives. Its only a matter of time before you die at your own hands. Amusing, really.

"Sister, won't you have tea with me? Bless us with your grace."

Rezef chuckled, a mockery in his tone. Despite his innocent face, everyone knew how much guarded he truly is.

The servants would just stare at the crazy Princess, afraid of your next move.

"Now now, no need to be upset with that frown. Don't hiss, its unbecoming of a lady your stature." Rezef mused, calling a maid to brew Lumine's tea.

Your someone he cant control. Unpredictable. Isn't that your charming point? His in for a challenge to tame you.
