Girlfriends...or besties?

To a historian they're all "roommates"

Only "The Moon on a Rainy Night" and "Monthly in the Garden with my Landlord" are tagged yuri

"The Secret of Friendship" is not tagged yuri and seems more like a het work from the plot

"Nana" is not tagged yuri, the plot suggests it might but I'm not risking it after having been burned by a yuri bait before
