This is one of the best manga I've read in recent times. It's beautifully written, thought provoking, humourous, drama in the right amount and no unnecessary ones, romantic, emotional. I laughed and teared hard reading this series. The "science" and resolution part of the series is a little flimsy, but it was just a minor issue. What was amazing is the journey and the characters that I grew to love. I feel a little emptiness after finishing this series.
