1 part Complete Harry takes great pride in being everything that his father hates. He loves finding new things that his father despises and when he does, he integrates them into his personality. It's like a fun little game that Harry gets to play. The only thing that Harry didn't plan for, was that he truly does like boys, it isn't an act, and it isn't just because his father hates it because it's hard on him and his public image.
Truth be told, it's hard on Harry too. He hates seeing the articles that come out about him and his newest fling. It hurts to read about how he's a playboy and uses all these boys and the few girls around him just because he has the power to do so. It's not true. None of it is true. Harry felt genuine feelings for every person he's ever been with. Most of them use him. They use him for his money, they use him for his power around the city, they use him for all that he's worth.
He's worth a lot to be fair. He wishes he was worth more than who he is. Harry wishes to be loved for being just Harry, not Harry Styles.
