'Promised'

"We're like a family, you know? I'm like the Mum, you're like the Dad and Happy's like our son"

"Huh, I guess you're right"

Love. There's so many types and almost all are indistinguishable. It's impossible to find the point where the type of love you hold for someone changes into something else.

I'd come to this conclusion while observing and comparing the Edolas Fairy Tail to the original Earthland version.

I live in a world where everyone is my family, where everyone loves everyone else. It's hard to tell where that love crosses the line and plunges deeper and deeper until you can't escape the realisation that you're in love with them.

I was 9 when it first happened, Natsu and I were busy raising happy, our 'dragon' child who was really a flying cat. Natsu was my best friend, he was dense, oblivious and oh-so childish. I couldn't love him; right? Wrong. I fell in love with him, nothing could stop me. We were young and naive. We laughed, smiled and promised. Promised that one day; one day we'd get married and have a dragon child of our own. But we should have known that promises can't always last forever. And we didn't account for the future, that put a blockade in our midst.

I often sat in the Edolas Fairy Tail Guild and scouted for potential relationships; I was Mira's sister after all. One couple that struck me as odd was Lucy and Natsu, sure I'd never met my Lucy but I still couldn't help but have my heart fill with sorrow and jealousy whenever I thought of them. Natsu promised me; but he also thinks of me as dead. Just how far do childhood promises carry? Are they even valid in adult life? Do they not count for anything?

When I returned home, everything was different. Relationships were at different stages to Edolas. It took me awhile to get my head around everything. But one thing that confused me the most: Lucy. She was the embodiment of Celestial magic. Kind, forgiving and beautiful to top it off. Nothing like the scary being that haunted the Fairy Tail Guild in Edolas. But she was also Natsu's friend, even if Natsu looked like he had already crossed that line and plunged deeper and deeper for her. It stung, because we made a promise and Lucy deals in promises. Because celestial mages never break their promises.

Even if it's sad and breaks my heart. I've learnt the true value of a promise. Lucy never promises something she knows she can't deliver. Maybe I should be of that belief too. Because in another lifetime maybe I was meant to be with Natsu, but events occur and not everything is as it maybe was meant to be.

But next time I take that plunge, across the family line. I'll be ready. And I'll make sure there's nothing standing between us that could get anyone hurt because family comes first. Always; and promises, they come second.

AN: Hello, I haven't really written fan fiction for Fairy Tail yet, but uh here's the first one..I guess. I just sort of thought about this idea of Lisanna accepting that not all promises can be kept. Even if they seem like they will forever be held true. And honestly I wanted to write something that shows Lisanna can accept NaLu and won't just be the jealous white haired animal she is sometimes made out to be (even if it's for plot benefit). So uh thanks for reading I guess..?!
