It's really a stunning manga in all aspects; the characters are sooo interesting, and there is a lot of character development in it. And both main characters are unique, and they are truly a fantastic couple (but prepare yourself, there is quite a big age gap between them). And oh my God, I had an eye-orgasm every time I looked at it, really, I had to inspect the drawings for minutes even though I read the pages very fast. I can say it's one of the most beautiful mangas I've ever read! (If not the most beautiful.) So yes, the art is the best partof it. The base story is quite simple, nothing interesting, it doesn't really have dramatic scenes (perhaps a few at the end), even problems like jealousy or arguments aren't explored a lot. The emphasis is on the developing relationship between the main characters, and that was shown outstandingly well. The fact that both of them have a bit of a sassy personality makes it even better.
