Tonari no Kaibutsu-kun, Gekkan Shoujo Nozaki-kun Recommendations
Both have dense Male leads
Both are hilarious with random odd situations. While Nozaki-kun is more inclined to be a parody of the whole Shoujo Genre (lots of elements from popular series will come up if you notice) Kaibutsu-kun revolves more within the Shoujo genre, but creates fresh comedy out of its crazy characters.
Either way both have good set of different funny characters, great fresh humour, and an ensuing romance. You'll love both of them!
The art is kinda similar too.. though Kaibutsu-kun is more pop with brighter colours.
Tonari no Kaibutsu kun has similar comical elements but it's slower than Gekkan Shoujo.
If you like Tonari no, you'll definitely love Gekkan Shoujo
short, feel good, romance, school life animes
The two of them have a few similar aspects.
+ Both have good humor, romance and high-school setting.
+ Really lovable set of characters.
+ Great 'Slife of Life'-ness
- Gekkan Shoujo is, of course, more towards shoujo side.
both are (really funny) comedic romances, with different characters and love plots to follow; although sounding a bit daunting, very easy to keep up with. love triangles/squares and rivals in both.
