Sirius wonders what she feels when she looks at them, that jittery feeling in her stomach when they make eye contact. They like all the same things, it's like they were created to be... friends. Yes, that's totally it! Friends!
She doesn't know why her gaze lingers, or her heart beats out of her chest, she doesn't know why her fingers nervously twirl her hair when they're nearby. What if they don't like stuff the way she likes them? What if they don't like pranks? That would be horrible! She loves pranks!
They just have to be friends! They're so similar! But she feels like she can't breathe when she's around them... That's normal, right? It's just nerves, completely platonic nerves. Remus keeps telling her it's a crush, but she doesn't — won't — believe him. Why? Because she swears that it's not! No way!
