Harry. He's eighteen years old, rude, cocky, and outgoing. Once you get to know the real him, he's sweet, kind, caring and funny.
They have been going the same school together for years. They know eachother but don't know the real them. Harry has his own friends he hangs out with and she prefers to be left alone.
What happens when one night, Harry is sent by his Mom to give Ariana's Dad something and sees something he shouldn't have? Will he protect her or leave? Will they start becoming friends or more?
