Super sweet (and steamy) manga. Gave me warm fuzzy feelings for the characters. The only thing I did not like has a slight trigger warning:

Spoiler

he hits her TWICE and there are NO CONSEQUENCES??? She's not even mad??? I guess one of them you could argue he hit to to snap her out of hysteria, but wow rude. Did NOT like that at all. Both instances showed up in the last two or three books so they had me utterly in love until then

and it would have ruined the series for me if it had happened earlier. (As it stands, this would be a five star manga if it had been left out entirely)
