Loved it :D
I thought it would be the usual shoujo manga, but I was totally wrong.
The time travelling plot was very interesting and I did not guess what will happen next. Also, it was a happy ending :)
The reader will experience laughter, sadness, pain, love, friendship, brotherhood, etc.
The manga has an unique and beautiful art. It has awesome characters where at first when you get to know them, you think they are in a certain way. However the more you continue reading, you find out the reasons why they are in that why, learn to understand them and love them. Moreover, an awesome story ^_^
Furthermore, this manga is not that long if you want to read something fast. It took me only 2 days and it can also take you one day. It they do an anime for this manga, I would definitely watch it :D
Worth reading :D
