The twins

Hadrian (Harry) Potter is the brother of the boy-who-lived, "Caspian potter". Because he's not the "golden child". He gets neglected by his family. Everyone except his godfathers. When he's about 4-5 he realizes he may not be the only one with a hard life, and so he starts placing 3 presents under the tree to be given to three people each year. Little does he know that he is what keeps the three mysterious people going in the dark. Will the three sad friends meet their secret admirer?
