I'm happy that both girls are being supported, and will keep rooting for the poly route.
I have to say, the comments here are strangely amusing. When Mei spends time with Rinna "Oh, she's going for Rinna, so much for the poly route." When Mei spends time with Sayo "Oh, she's going for Sayo, so much for the poly route."
Seriously folks, she's developing her relationship with both girls. Just because a short arc focuses on one rather than the other, that doesn't mean the other is being abandoned.
i hope the author won't pull of the i like this girl more route because its been setting up with the poly route ending i just want all of them to be happy and i hope rinna will open up to sayo more, like they already kissed lol so i hope it ends up with a poly route take the L single shippers
