Well, as this was (sort of) requested, I am now writing an Allen x Lenalee. It's my second, so don't be too judgemental. And for the sake of sweetness, Lenalee has long hair.
I do not own D. Gray-Man.
He treasured those times beyond belief.
He treasured those times when they would just sit together, her back to him.
He treasured those times when his hands were busy braiding her hair.
She treasured those times too. When she could just lean back her head slightly, close her eyes, and relax... Those times...
Those times were valuable, precious.
They were rare and far between, only when the two were off on a mission and had time for it in the evening, if they weren't so tired they just fell over without another sound.
Or if there was anyone else with them. No. No, those times were far too precious, too highly treasured, to have any other person intrude upon or even witness. Therefore, they were taboo when at home, too... That, and her brother would tear him to tiny pieces if he even got the faintest idea they had any kind of interaction that was upsetting the delicate balance of friends/family(in a cousin/sibling sort of way)/platonic in the newer meaning of the word.
Even Timcanpy was dangerous at those times, those precious, precious times, as he might be either bribed, threatened, or blackmailed into showing it to somebody who could use it to endanger at least one of the two...
Although there really wasn't more to the secret side of their relationship than simply sitting cross-legged on the bed, the couch, or even the floor (once on a table, but that had something to do with rats... Timcanpy ate those). When the braid was done, Lenalee would turn around and smile at Allen.
She would often hug him too, depending on her mood. Lenalee was a very touchy girl (at least according to Allen, who had been raised to think of touching as something more than just contact... It was something to respect, which could convey messages, long and short, secret and well-known, loving or hating), though, so the chance of a hug was great. Sometimes, so rare the times could be counted on one hand, she had given him a light kiss on the cheek.
She had really needed the comfort of the treasured time, then. She had been upset, emotional, wounded, or something else, and had welcomed the rare treat and the closeness.
But there was a reason aside from excessive gratitude why those peck were so rare, it was also because she respected those times too much. Respected them? Yes, yes indeed. Because they were pure, heartfelt, something only they had, a time when demons, brothers, masters, innocents, and comrades could all be forgotten. Even the whole, beautiful world that they fought each day to save could be forgotten, for they were the only ones who mattered in those thirty minutes or so it took to slowly form the braid (including brushing the hair), before they then set to undoing the work and brushing any knots that had come.
Often, yet another embrace would be exchanged then. The two would depart for to their sleeping quarters (or Allen would depart, as that was simply what felt more right to them).
The next day, everything would go exactly as if someone else had been with them, they never mentioned those times.
Okay... A little weird. ^^; Hopefully fluffy enough... That you choked on it as it went down your throat! (Evil laughter.)
All right, as long as it was very fluffy, I'm happy.
Now, this is my second D. Gray-Man fic, and I'm still not sure I got it quite right. Would you please send me a review telling me of what you liked/disliked? I need it for your sakes as well, you'll be reading my stories.
