Gekkan Shoujo Nozaki-kun is about a high school girl, Sakura Chiyo, who has a crush on her schoolmate, Nozaki Umetarou, a shoujo manga artist. She tried to confess to him but was mistaken as a fan of his manga and ended up as one of his assistants. Then, revolving around these two, the story goes on.
Sounds a lot like a typical shoujo romance, right? Let me correct that, GSNK is all about comedy. Bits of cute moments here and there but mainly comedy and it's done right.
While the plot is simple enough to be summed up in mere sentences, the characters are definitely the strongest point of this anime. The main cast consists of seven. There are four guys — the mangaka, the self-proclaimed playboy, the drama club senpai plus the basketball kouhai. And three girls — the heroine, the oblivious Lorelei and the prince of the school. Yes, prince. You read it right. Individually, they have their quirks and are so likable you'll have a hard time picking a favorite. (In case you happen to hate all of them, fear not, there are also lots of tanukis)
The best parts, however, are their relationships and their interactions. Thanks to the creativity of the author, this group of characters plays off of each other so well you can randomly throw any two or more of them in a normal high school life situation, add some shoujo manga-related topics, think from their perspectives, let them converse for a while and get a laugh or two out of it.
Basically, that's what GSNK is all about.
The animation is what you would expect from a 2014 anime and the art style is faithful to the original manga. OP and ED songs are very catchy and fit the light-hearted atmosphere of the anime. I actually like the opening song a lot. As for other OSTs, I honestly couldn't catch them because I was busy laughing. The VAs are great. There're many famous names in the cast (Miyano Mamoru is the protagonist of Nozaki's manga, mind you) but my favorite is Ozawa Ari. She portrayed Sakura perfectly.
For enjoyment, I didn't read the manga before and I enjoyed watching the anime very much. I also prefer this anime version even after reading.
Overall, Gekkan Shoujo Nozaki-kun is fun, refreshing and very easy to get into. Personally, I love it so if you're looking for something different, if you like comedy or if you want a shoujo version of Gintama, I highly recommend this anime.
