I'm very impressed because:
I can't read it if the art is bad, and I hated the art of this manga. and yet! I continued reading (even tho I wanted to drop it after seeing the art in ch1). that's really impressive. the story was so gently paced and sweet and fluffy that I couldn't drop it.
however, in ch6 (which is a separate story), the art got so bad that I did drop it :(
