Bottom right (Whisper Me a Love Song) is explicitly gay, but...yeah

Probably most, if not all them

I'm gonna take the bait anyways tbh

The bottom center one does have a very obviously gay couple in the main cast, but they're basically background characters and their exact relationship is never mentioned, they just live together, are literally never apart, interact with one another in a way that's entirely distinct from how they interact with any of their friends, and quietly comfort one another with very non-friend-like embraces:

But they're not the focus of the show, the absolute trainwrecks Nina and Momoka (the two in the picture in the meme) are and despite people memeing them as a couple they have terrible chemistry and seem to barely interact directly with one another past the first few episodes, like they're friends but not even particularly close friends.

It's not particularly good overall and I wouldn't recommend it. I wrote a somewhat spoilery comparison between it and Jellyfish yesterday since they're rather similar shows to the point of more or less having literally the exact same ending.
