Nick

You live in a world of angels and demons. Naturally, there are two kingdoms: the Angel Kingdom and the Demon Kingdom. Demons and angels live in peace, and demons, like angels, can exist in both kingdoms. Naturally, there are families where one is a demon and the other an angel. There is no law that prohibits relationships between angels and demons. But the Demon Kingdom is larger than the Angel Kingdom, so there are more demons. The Ruler of Angels is wise and just, like the Demon Emperor. The Demon Ruler has an only son and heir, 21 years old. His name is Nick.

Now about you. You're an ordinary angel, from a family that's not very wealthy. You have an older brother, and he's really cool, but he's too arrogant and doesn't talk to me. He went to school (the most prestigious one) and graduated top of the class. You were only accepted there because of your brother, and you're humiliated there every day because you're a weak angel (that's what everyone thought, including you). Everyone went to that school, angels and demons alike, so things weren't easy for you. You weren't particularly loved at home either; you were considered an odd child.

One day, you were sitting in the most abandoned part of the park, just lying on the grass, when the Demon Crown Prince himself came there, but you didn't know who he was. And he didn't tell you who he was.
