Like a Ton of Bricks
You'd always thought it was a bit of a cliché to be honest. That someone could just realise that they'd "fallen for someone". You'd never have guessed it would happen to you of all people (you were never the type of girl to get involved with all that "boy nonsense" as you'd dubbed it). Yet it did. And when it did you couldn't escape it, so you ran from it (predictable old you - always running from things that scare you). You ran and you ran and you ran until it felt as if you might fall apart, but still you couldn't escape it. You were falling seriously in like (love was another one of those clichés you steered clear of) with this boy, this Scorpius Malfoy and there was nothing you could do about it.
Maybe it was the way you slowly became friends after all those years of acquaintanceship. You had after all known him since you were eleven, and everyone knows the whole "absence makes the heart grow fonder" idea is a whole load of bollocks, but that instead proximity enhances relationships. Or perhaps it was your shared interests, how you could talk to him about the strangest things and he wouldn't look at you like you were a nutter. Or perhaps how you were becoming closer and closer as the days passed, sharing your secrets, greeting each other with hugs, instinctively calling each other by fond nicknames.
Although, you're pretty sure it was that kiss on the head you recieved from him last weekend that did the trick (although you're still entirely unsure as to whether or not you imagined it). All you know it that when it happened (if it in fact did), it hit you like a ton of bricks just how nice it felt, how comfortable and safe you felt in his arms.
It was then that you realised. That you were so close to falling completely and utterly in like with this boy; something you'd never even come close to in the past considering your complete lack of dating history. All of a sudden you were taken over by these feelings and you just didn't know what to do. So you ran and you hid and you lied to yourself. You couldn't understand yourself anymore - what had happened to the girl that looked at all the short-lived relationships going on around her and decided that she wanted none of that? Was she now gone forever, shrouded by this new Rose, the girl who suddenly wanted nothing more than a boy to reciprocate her feelings for him?
That's the reason why you ran. You were so worried that this was the case, that you were changing yourself for a boy who could just as easily break your heart as make it whole. You were changing so rapidly, so easily, so unreasonably and it terrified you.
So you ran and you ran and you ran, always looking forward, never turning back. Never noticing that he was right behind you all the way, trying to catch up. Never once stopping.
