Well... some people may not agree with me but I gave this series a 10/10 because it has a great story ( and again this is my opinion) and like-able characters. After reading this Manga it reminded me of when I first read and watched my favorite anime series "Ah! My Goddess". Both have this kind-of feel good aura. I didn't put that into good enough words i'm sorry. After reading it you feel good and or happy. ( well that's at-least how i felt)
In this particular Manga they spend a lot of time on the relationship of the characters and how they handle the obstacles that come with said relationship. I like these types of things for some reason, I guess it just interests me. The characters were well developed and the story was great. However I think that the story itself could be longer because it kind of ends after they go public. I felt the exact same way with Zero no Tsukaima one of my favorite anime. I feel they could have shown a little more of the life they share now as an offically married couple.
( Thank you to those who to the time to read my review and I hope you found it some-what helpful )
