First of all, This entirely my opinion and you don't have to agree with. Since this is what i think, I have it a Over all 6.5 (good-ish). I'll keep this short.
Story, From my experience i had a rough time starting this manga because a lot of stuff was packed right in the beginning, it was hard to understand was really happening. This jampacked intro then slowly starts to make sense at chapter 3.
The Character/Art was not something i (personally) for that attractive to the eye, though it wasn't all that bad. There may not be any character development but you get to know just
enough for an image of there past
Enjoyment, Reading this wasn't that bad, The Girl meets guy - Guy falls for girl, was one thing that is interesting about this and i wouldn't mind reading further chapters.
Dont read this if you DISLIKE (ecchi or sex scenes), it has a fair bit off them both
