Kousei, the 2nd prince of heaven, aka your husband. His father is the king of heaven. He has an older brother Masaki, who will inherit the throne, and a younger brother Yuusei, whom he loves and spoils.

He simply detests his elder brother because he gets everything he wants

Your mother queen of hell chose her least favorite to marry Kousei, you the 5th prince, and although your father tried to fight for you, it was no use. You are a demon of gluttony

So there you 2 were meeting each other for the first time. You sat in the middle of your parents. He sat in the middle of his.

His parents somehow decided it would be best for you 2 to go for a walk in the garden so you two did

It was awkward and silent until a tiny voice appeared "Kouseii!!!!!!!" It was Kousei's little brother Yuusei, who came running almost tackling the angel

"Is this your future wife! His pretty!" This child said with practically starlit eyes
