ScorpiusRose
Rose and Scorpius, they've been best friends, ever since Albus and she stumbled upon him in the Hogwarts Express. He had been doodling on a spare piece of parchment paper; he had been sitting there, alone, looking perfectly comfortable.
Naturally, Albus and Rose had introduced themselves. Scorpius had invited them in; they'd shared candy, memories, laughter as the train sped closer and closer to Hogsmeade Station. They'd all spoken with Hagrid; they'd confided their Sorting fears and consoled the fourth person on their boat, Caroline Lee, who'd missed her mum.
In the Great Hall, they had been no exception to the strong emotions caused by the Sorting. Rose had been excited (superbly so), Scorpius had been apprehensive, and Albus had been green with fear. It turned out they'd worried for nothing, at least Rose and Albus; they all landed in Gryffindor House, home to the brave and the daring.
First year passed; in June they'd separated, Rose off to camp, Scorpius to his home, and Albus to Teddy's house with Lily while James went on vacation with the Kerry twins. The second year was eventful as well; the three of them found themselves in hospital beds once more, in Madam Pomfrey's care. The new Headmaster visited; Slytherin won the House Cup, much to everyone except the House members' dismay. Dominique, the Slytherin Weasley, the only Slytherin Weasley until then, glowed with pride.
The boys had helped her again in the third year; the year where Hugo slipped from her. He was no longer her baby brother; he was an independent, secretive, wily Slytherin now, full of House pride, with new friends; it seemed he didn't need Rose anymore. The third year was a year filled with revelations.
Fourth year, things began getting awkward. Rose had always had a crush on Scorpius; butterflies and a quicker-paced heart whenever he smiled or did something that made him look simply adorable, like when he brushed his messy hair from his eyes. She had dated others in the past years; he'd gotten his first kiss from a cousin of hers. There was nothing written anywhere that they needed to be together, but it seemed that fate was manipulating them once again.
He found himself getting more and more attracted to her; he found himself watching her, loving her more every second. He couldn't have known that she had a crush on him; he however did know that she was dating Logan Miles, a fifth year Slytherin known for his jealousy.
He couldn't have known to not kiss her in the broom shed after the last Quidditch match; Ravenclaw against Gryffindor.
But he kissed her, and was ashamed to say that he had enjoyed it, before she ended it. Before she proved that she was a Weasley, once and for all, even if she had curly brown hair and (mostly) her mother's face.
Scorpius wasn't the type of boy to overtly display his feelings; he preferred keeping them inside him, even when it hurt so much. His childhood had taught him about that much, and he was convinced that this made him strong. This was what his family did, anyways; buried those feelings deep.
He should have known that the Malfoy family's doings were not exactly exemplary, too.
