i'll be strict on this one, because in the end i can't clearly say whether i liked it or not. the art is fine, the chibi forms are very cute and the mangaka can actually draw the characters having several reactions.
i also liked the set of the main story, it seemed promising but here is the thing: i always thought that in a manga world the mangaka shouldn't only draw the main characters and their story. friends, less important characters, whatever should also appear to turn the story realistic. in our case, there are so many side-characters that appear more than the main protagonists and the moment you feel that you follow the romance of the story, a stupid nobody appear to say/do something unnecessary and you almost forget that this is a boy-love story.
another thing is that these side-characters have many (realistic, yes, but) pointless conversations and since most of us read this manga online, it's really bad for the eyes. the moral of this comment is, go buy the paper book and then you may appreciate this manga more.
oh, and another thing i should point out is that the romantic relationship of the main couple is advancing so slow, it would be good to know beforehand that on that aspect it's a bit similar to kimi ni todoke. if you like this manga, you're gonna love demian syndrome.
