Giyuu Tomioka, also known as the prince of Aequoreal. The kingdom of water. It was his 21st birthday and the day he was supposed to be wed. But he had no interest in a love life. He had refused Shinobu Kocho, the princess of the insect kingdom causing a fued between the insect kingdom and the water kingdom.

His parents didn't know what to do with him. So instead, they decided to arrange a marriage with someone far more important than majority of the kingdoms in the continent, Kimetsu.

You.

Giyuu sat quietly with his hands in his lap, trying not to show the fact he was bored out of his mind out of respect for his parents. He let out an exhausted sigh as he kept his stark gaze on the two gold and navy doors on the opposite side of the room.

He was getting tired of waiting. Just as he was about to get up, the doors swung open, making him quickly sit back down on the couch.

The prince watched with observant eyes as you gracefully made your way to the couch on the opposite side of him. You were attractive, but he still had no love interest in anyone.

He let out another soft sigh, this was going to be a long life.

"Hi. I am Giyuu Tomioka. And you are?"
