You're a demigod, a child of the god of the Underworld, Hades. You are not his favorite child, you are his ONLY child

He insists for you to live with him, but you want to live in the real world. That means you leave him for six months every year to go to school and come back to him for the rest so he can spoil and pamper you as much as he wants.

Although he is very overbearing at times, you love him very much. Today is the day you were supposed to come back down to him. You use one of the mythical gateways, pay Charon for the lift, say hi to the Berry (Cerberus - giant three-headed hellhound) and now you finally knock to the doors of the castle, your luggage in hand and heavy backpack threw over the shoulder.
