The male lead reminds me of Mikoshiba from Gekkan Shoujo Nozaki-kun, except instead of stereotypical pretty boy pick-up lines, it's stereotypical pretty boy trash talking that he involuntarily spouts.
EDIT: Well I've finished it, and it was pretty fun, cute too. It's a shame it got axed.
Now that I think about it, the heroine reminded me of that of GSNK too: she's shown to be a liiiiitle bit obsessed by Fujiwara, which clouds her judgement when it comes to him.
