***I do not own fairytale, but I wish I did***
Natsu's POV
It all started with a bet.
I was babysitting Asuka and I bet that I could beat her in a shooting contest. She told me that if she won, I had to do whatever she said. I hadn't expected to lose, but I should have known better since Asuka is the daughter of Alzack and Bisca.
At first, it was just being her horsey, and that honestly wasn't too bad. I loved Asuka and I loved to make her smile and laugh. Then, at the park, I had to be the bad guy as we played cops and robbers. Again, that wasn't too bad. Asuka is such a great kid.
I think Asuka really started abusing her power when she hit me in the face with her gun and made me jump in the water. That little girl can be a real menace. But then she goes and gives me those puppy eyes, and how am I supposed to resist that?! She can be such a cheeky little brat, going on about wanting to go on a mission.
Even Lucy gave in to Asuka's begging, and Lucy is usually the reasonable one. We went on a bunch of easy missions that Happy had picked out – but it was sooooooo boring! I wanted to beat someone up already! (Where was Gray when you needed him!)
Then Asuka bought that keepsake snow globe, which made her start thinking about her parents. Thinking about her parents apparently made her think about kissing and she demanded that Lucy and I kiss!
I couldn't see what the big deal was. I promised the brat I would do what she said, and kissing Lucy wouldn't mean the end of the world. Lucy was my best friend, my partner…we shared a bond that couldn't be broken. Who cared about a silly kiss?
It was almost like I was seeing Lucy in a different light. This would be my first kiss too, and it wasn't a bad one. I cared so much about Lucy – this could only make our friendship stronger. BUT THEN I ENDED UP KISSING HAPPY INSTEAD!
WHY LUCYYYYYY!
-Later that Evening-
"Lucy? Why didn't you want to kiss earlier? What's the big deal anyways"
Lucy's cheeks went red and she yelled at him, "BAKA! It's not just a kiss!" Then, so quietly that I almost didn't hear, she whispered, "it's my first kiss and I want it to be special."
I looked at amazement at Lucy. Who knew a first kiss was so special? I was about to say something when –
"HEY FLAME BRAIN, YOU WANNA GO?!"
"BRING IT ON STRIPPER!"
-Later that Night-
Natsu thought a lot about what Lucy had said earlier. It kept bothering her that she wanted her first kiss to be so special. He just couldn't see her point of view. But he loved Lucy, she was her nakama and he wanted to make her happy. Natsu decided then that he would make Lucy's first kiss special.
