Then, it seems to wind up getting closer and closer to the kind of harem show (even if the main character is technically female) of the exact same type as the series started off bashing simply by sheer Flanderization of the original premise.
I think people are seeing a harem when there really isn't one. We have exactly ONE girl who wants to get into Tomoko's pants (Uchi); the rest are friends with their own sets of neuroses (Yuri is an introvert with attachment issues; Masaki is a delinquent with a Peter Pan complex; Mako has Chronic Hero syndrome; Nemo is very manipulative and likes to pokes Kuro's buttons), or acquaintances of said friends (Asuka is the class mom; Akane is a bully hunter).
Could someone please fill me in on what has been happening in the manga to result in artists drawing Tomoko with a crazy yuri harem?
Technically, only Ucchi has shown any kind of romantic interest in Tomoko. Everyone else are just friends (Tomoko now has four -- Yuri, Masaki, Mako, and Nemo) or mildly interested in Tomoko's weirdness (Asuka, Akane).
