Unnamed bond

Fanfic of LenaMiu

We aren't friends, nor are we best friends, and certainly not like siblings-it feels different. It isn't like that. I have a best friend, I have an older sister; this is something else entirely.

I almost used the word "girlfriend," but it felt as if a string was holding my tongue back. Yes, a line has been drawn-not by me, nor by Miu, because we've never spoken of this; everything just flows. Instead, it was drawn by circumstance and the weight of our professional responsibilities.

This bond is nameless, but I know how it feels. It feels as though she is home. She makes me comfortable; spending time with her only makes me want to stay by her side even longer. She makes me miss her; she makes me want to protect her; and she makes me want to see her smile always, because that is what makes me happy.

Miu is like fresh sunlight. Miu is like the scent of my favorite lilies. Miu is like a melody that I could listen to for hours on end. I am always thinking of her, unconsciously memorizing every little thing she likes or dislikes.
I want her to always be smiling. She can fly with wings that others might not see, but I see them. I want to see her shine.

So, what do you call this bond?
