There was lesbian stuff in this manga? I can only remember some flirting and lewd (het) characters in general.
What? Wasn't this whole comic just a bunch of weird girls lusting after each other?
This. At the very least a bunch of characters were bi, a lot of characters in his works are bi, even males from what my memory can recall. Anyways, this entire manga is about the main female character "accidently" building a harem of girls, while originally trying to get the boyfriend. It's basically Scott Pilgrim but if Scott Pilgrim mostly ends up with a bunch of boyfriends. The series definitely wasn't het focused despite the original goal of the main character, as she ended up with a bunch of girlfriends.
