I stumbled across this manga while I was looking for a manga I'd previously read. I don't really like most of the manga with the romance theme as they are often all the same, but this had such a gripping plot. Of course the romance is the centre, and I certainly think the main characters suit each other, but the plot and backstory, even the character development is very well thought out and I found myself not been able to stop reading.

If you like romance, but with a bit of action. I highly suggest Dengeki Daisy. (Maybe if enough people like it, it'll get an anime)
