Since this is a one shot (a VERY short one at that), there's not much to say about it. I'll start my review:
ART
I really liked the uses of warm colors in the art, it reminds me of the various children's books my mom read to me when I was young. Other than the colors, the art style is kind of cliche; there's nothing in it that will make you remember it forever. It's normal manga art style.
STORY
Like I said, this is a very, very short one shot, and the story is very linear and average.
Character
It's short, so you don't get enough time to fully enjoy the characters. There's two human characters and a fairy, and everyone's basically nice to each other.
Overall
This is a nice story if you're bored and want something cute to read. If you're looking for a cute shoujo ai short story to waste a short amount of time, then this is it.
