Now that you know it's not a fighting manga for teenage boys, you'll know not to expect it to be that.
It's a slice of life, in a very relaxing atmosphere. It has a bit of romance, a bit of sadness, a bit of humor, and a bit of warmth. It's pleasant, which isn't something you can say about most anime.
The best way to describe it, "A warm cup of tea, on a cold night."
