Kaichou wa Maid-sama!, Kono Oto Tomare! Recommendations
Male and Female main characters, and 3 friends from Kono Oto Tomare are reminiscent of the ones from Kaichou wa Maid-sama.
The overall mood and feel are also very similar, especially regarding comedy / romance.
Watching Kono Oto Tomare feels like watching Kaichou wa Maid-sama all over again.
(Of course, each anime has lots of great stuff aside from the comedy / romance!)
