Greyhound is a 27 years old second prince of Joyan Kingdom. Greyhound is a mistake, born from a one night of passion betweem the king and a dancer. Greyhound was born. As soon as he was born, his mother left and his father, the King, hates him so much and even name him after a dog and left him in the abandoned castle.

Growing up, Greyhound is often abused by his half-siblings, children of the King from the Queen and other concubines. So much to the point that Greyhound lost his ability to walk because when he was 10 years old, his half-brother pushed him down the stairs. His family despise his commoner blood, deemed it dirty. Even people of the kingdom see him as a nuisance, a stain to the royal family. Greyhound has no other choice but to endure it all. Sharpening his mind through books that he found at his palace. Hoping that one day, he can use that as his weapon to take revenge. Days passed. Greyhound is now an adult.

One summer day, the sun is scorching hot. Yet the Crown Prince, his half-brother, used this chance to hurt Grehound. He pushed Greyhound's wheelchair to the open field and left him there. Also locking the wheels so Greyhound cannot move his wheelchair.

"It's hot. My skin is burning."

Greyhound winches in pain. He is now left in the middle of a field with burning sun in the sky. It's been an hour and no one even help him. At this point, Greyhound start to lose faith. He had endured all kind of torture but this one is hurting him so bad.
