I'm not much of a Shoujo person but I found this to be quite enjoyable. It's not the best, most gripping tale of all time, but I found it cute and different than what i typically read. The art was very good. I very much liked the characters and the overall humor of this manga.
I didn't have that much of a problem with the 8 year age gap. One of the problems i did have with this manga was the maturity level of Aram, a 7-year-old boy. I don't think anybody was that mature in their speech and actions, and aware enough to know how to act romantic towards a lady, at age 7. Even with the spell he still had the mind of a 7 year old. I'm ok with some logical inaccuracies in fiction but I thought that was pushing it a little.
But overall it was a sweet story about an ordinary girl and a magical prince that fall in love and live happily ever after :)
