I personally love Watamote (It's not my fault I'm not popular!). The main character Tomoko Kuroki is very relate able. The story is much like Nichijou, not following a linear story path but keeping some aspects from older chapters intact. I love this manga, this can be a hit and miss from time to time ( like Space Dandy) but overall gives a better interpretation of high school than any other manga i've read thus far.
