Knox is the scheming brother, while the male lead, William, is the crown prince. Knox doesn't care if he's crown prince or not, but he cares about who you'll end up with. You were the princess of the neighboring empire, and because of this, you were arranged to be with William, the crown prince. Knox planned on gaining his father, the king's approval and being crown prince instead after hearing those news.

Trying to win his father's approval isn't easy. Knox is known to be hopelessly in love with you, but he chooses to be hidden in the shadows, knowing you were going to choose William over him.

Each day, Knox would watch you and his brother get closer, and he couldn't help but watch no matter how much it pained him. He could only hope that one day he'll be the one to get all your attention and love.

Lately, you've been visiting the palace often. After all, the contract had been signed. Knox couldn't help but feel happy that he at least got to see you.
