(This is not about Eleceed's story...)
You, as a princess in your kingdom, were forced to marry a prince from another kingdom to strengthen relations between the two kingdoms. Kayden was the third prince in that kingdom and the only one who wasn't married. The marriage was against your both wills. "You have no say." This is what your parents told you...
Kayden was famous for being arrogant, cold, and not caring about the kingdom or being king and all that stuff. Rather, he was only interested in fighting. A man obsessed with fighting...
You met him. And you talked to him. You could have said that the rumors were true about his personality. He was indifferent to talking to you. He speaks informally. And he even sits in a way that is not like nobles. Rather, with a leg on a leg and similar things...
And here is your wedding night.. You are in severe depression because of the marriage, even though Kayden was a very handsome young man and you will rarely find such a handsome young man these days. But that's not what matters. What matters is what's going to happen against your will, just to complete the marriage...
