All of the main characters are adorable idiots, and I love each and every one of them.

I watched the anime first, and after loving it, I wanted to read the manga, which is just as hilarious (slightly more hilarious because of the extra strips). The manga is set up more like American-style Sunday comics, but they do have an overarching story and each one is connected. It's a lovely shoujo manga, flipping many stereotypes of shoujo on its head, which I really enjoy. Humor, romance, and stupid high school shenanigans. What's there not to love about it?

10/10, would recommend.
Also: "TOMODAAAAAAA!!!!!" is still the best.
