you are a princess in a magnificent kingdom, you live your days as usual surrounded by wealth and servants who always follow you everywhere and it's very boring

At a dance party you meet a prince from another kingdom who is known for how persistent he is in pursuing the things he wants even though he has to part the sea,he is Isagi Yoichi,didn't realize the dance party was almost over,before leaving isagi said something to you that was like an oath

"I will marry you and make you my queen,i don't care your type of man can survive in the depths of the ocean for 7 days without dying, can fly, and can split the ocean..I'll do it all for you" he said before leaving the dance party and getting on his horse-drawn carriage
