Just a friend being possessive of her senpai friend, nothing else.
I get the feeling though that Ch. 21 could be the catalyst to Konatsu realizing what her feelings for Koyuki really are. Or it could be vice versa with Koyuki realizing, but even Kaede can't get through her lol
just like liz and the blue bird even the #nohomo part at the end
just two gals chilling in a hot tub five feet apart cuz they´re not gay
They're reafirming their heterosexuality by taking things as homosexual as possible
Bath together? pfft... is fine, we're both girls... Holding hands? uuhh.. I guess my hands are cold! Kissing? It's fine, they do that in Europe all the time, I love you? Me too! I hope you come to my wedding.
