This is one of the manga's I recommend to friends that enjoy a lighthearted story with romance intertwined. I wouldn't say this manga is one of my favourites, but I always find myself thinking back to it time to time. It's a mange that you can't forget very easily.
I say this because the first couple of chapters are lighthearted until you get hit with something you did not expect.
If you are losing hope in this mange, I recommend you read until you get to the middle because that is when the story really begins to launch.
Overall, I'd give this manga:

STORY - 9
CHARACTERS - 7
ART - 8
