I'll Make You Mine
It started in fourth year, with a simple panic attack. That's when everything changed.
Draco had always been in love with Harry, since he met him in Madame Malkin's. He pretended that it was hatred because it made the pain easier to deal with. He never thought that Harry would become his friend- the idea was laughable to him. But one day, he said two simple words, and Harry became his best friend. He made a promise to himself that he would make Harry his and he intended for it to happen.
Harry had always thought that the Slytherin Prince was attractive- and maybe, he had had a small crush once upon a time. And maybe, he still did. And he was falling deeper and deeper, but he was sometimes stupid, and sometimes made mistakes, and having a crush was definitely a wonderful place for those traits to hurt him. But Draco? Nothing Harry did involving Draco was stupid or a mistake. In fact, everything seemed to happen in a way that made Harry promising to make Draco his.
Pansy never expected to fall for a girl, much less a Gryffindor, much less a muggleborn named Hermione. But she did, and she fell fast, and it was a mess. She tried to push it aside, but all it did was make her chase after this girl more. And she swore that one day, Hermione would be Pansy's.
Hermione was a good student. She didn't get distracted. She didn't misbehave. She didn't let boys cloud her mind. But a girl... When Pansy came along, Hermione was caught blindsided, and though she tried to push her thoughts aside and push them down and forget them, they never went away. And somehow, she found herself wanting Pansy to be hers alone.
And everything changed.
