Who are we to fight the alchemy

Over the summer break, she sworn she’d just ignore him altogether. And for the first time, James Potter seemed to have decided to use the same strategy. He usually wasn’t the one to hold grudges but judging by the way he acted – as if she was invisible – Lily assumed he was really angry with her this time. She was aware she probably wasn’t completely fair to him, comparing him to the people who were most likely already sporting the Dark Mark. But her point still stood. He was arrogant and spoiled, never considering the consequences of his own actions. Marlene had tried to convince her multiple times throughout the years that James was a really nice guy when you got to know him better, but Lily wouldn’t hear it. And there was no point in arguing when the redhead set her mind to something.But what if, in the end, the child's play back in school was forgiven under Lily's rule? Because the sign on his heart said it's still reserved for her, and honestly, who were they to fight the alchemy? (The alchemy - Taylor Swift)
