Tomboy lead Tomo has been mistaken for a boy by her childhood friend Jun to the point that he doesn't see her as a girl (or so she thinks). Super funny all the way and adorable, I love Tomo and Jun so much and I'm glad they're finally making progress so far! Don't let the number of chapters fool you, it's a 4-koma manga with one page per chapter (usually, save for the omake.) It's a quick, refreshing, and absolutely adorable read.
Tomo-chan wa Onnanoko!
