It's a bit sad that the only yuri comedy manga that's actually hilarious all the time instead of just being cute or... embarrassingly crappy (looking at you, lesbian-family-runs-a-resort manga) isn't really about a lesbian couple. Sure there's some funny innuendo and they behave like an adult couple and all, but it's made pretty clear they're just close friends.
Not that I mind. Its' one of my top ten manga.
