“Your Highness, there’s something I’d really like for my birthday.”

“What is it?”

“Will you promise to listen?”

Then the man blatantly laughed.

But who would point out his arrogance – a young Northern Duke who’s not even afraid of the Emperor? He could even get a throne if he wished for it.

But it was just a sweet lover’s birthday wish.

“Alright. I swear.”

So, Juliet spoke lightly,

“Please break up with me. I don’t love you anymore.”

A fiance just for show. A succession of meaningless nights.
