This is a spoiler free review for the whole series, up to where it is currently out in English volumes (volume 4). I update it periodically as I don't like rating individual volumes and would rather rate the series as a whole. 

I read all four volumes of this series in a day because it hooked from the get go and had me kicking my legs at the romance in no time. Is it is just a fun time. The drama can seem a bit juvenile for the characters age at times but I think their backstory explains it enough for it not to bother me.
