The Prince and The Pauper

Astral and his twin brother Black Mist are both princes overruling the Human World with their father, King Godith. A boy, a simple commoner, has heard of Prince Astral and has wanted to meet him. Once he does, the prince seems like a cold, hard shell while his brother is even colder with an evil aura. That doesn't stop the boy from taking a liking to the prince of the kingdom. Once disaster strikes for the second time for Astral, the whole city is turned upside down again! This time, both prince and pauper lose someone they love: the prince's brother and the commoner's sister. They unite forces to find their siblings, and they find they have some...interesting feelings for each other. (Keyshipping, Yuma x Astral. This is my first romance, so please don't judge O-O")
