I love this manga, and will most probably read it again in 2 years time...

The story was literally amazing; it is inspired and one the rare heart warming ones where you can relate to the characters, also there were some arcs that I really liked, like the Hanahime Den Arc; you actually saw what kind of character Natsume and Hotaru were, when they stood up for Mikan. xD

I love the art as well, it is not overly detailed, and very simple. Just that sometimes you notice a strange ring shadow around their mouths...? (Maybe it's just me)

I especially enjoyed reading each character; for Mikan, she follows the typical naïve girl plot that most shoujos have, but not the type where you can get annoyed at. She's also one that grows to be mature, but she is in general a very brave, cute, comical and inspiring character.
It was also nice the way the author displayed Natsume; a cool, unapproachable guy that doesn't seem to care about anything, let alone anyone but as the story goes on, you can tell how much he loves Mikan, as well as for the people around him. (I might start crying now...! T.T)

As for Ruka-Pyon and Hotaru, you can tell that Hotaru sincerely cares about Mikan, especially near the ending. She's also displayed in a very comical way, with all her gadgets, hehehe. Ruka-Pyon, especially, was one of my favourite characters, although he was kind of a minor character, he still tried his best to support his friends and connected with a lot of readers' hearts. (Probably because he's cute as a rabbit! xD)

Despite being a long manga of 180 chapters, it was totally worth reading, there were a lot of feels, ships, but to experience the actual enjoyment I think you actually have to read it for yourself, as words aren't enough to compare.

Overall, I don't regret reading this manga, seeing as it was far better than the anime, you could see the development of each character slowly maturing each chapter, and it was nice to see that Natsume and Mikan could be together.
One thing I would say though, the ending was a bit... Crap. A lot of people say that they hate the ending, and personally, I don't hate it, even though it was a bit lacking. But I don't really see how you could improve the ending; it was left on a cliff hanger, imagine they found Hotaru, and had a happy reunion, would that have been better? Maybe, maybe not, but still I really loved this manga; the 180 chapters are worth the read, I would also read it again in 2 years, and definitely recommend it to readers that enjoy Romance, Drama, Shoujo and Comedy with a touch of Mystery, Action, and Psychological bits here and there.
