As a yuri fan and Mako x Yoshida shipper, I'm honestly disappointed by the raising in het the series had, but it's not a surprise unfortunately
But I guess that's on me, as a yuri fan, reading non yuri manga only brings pain and disappointment
To be fair, we've had like 8 years of yuri teasing going on and we have multiple gay characters. Over that time, the extra bits have leaned heavily into the gay stuff (there was literally one of best pairings and they were almost all lesbian iirc), and in general the "fandom" has been more yuri leaning. Hell, the group doing the TLing is literally /u/scanlations.
Now, do I think it's le epic betrayal or anything like that? No, not really. I guess I can understand why people feel that way, but I think it's very silly in general. That said, I do think that in the past year or so, it has got less funny and engaging. I feel like things are much less focused right now and that's to the detriment of the series. There have always been side characters and their separate arcs, but much of these existed in terms of their connection to Tomoko. As the manga has branched out, I feel that lack of focus has made it feel less cohesive and less consistently funny.
That's just my opinion though, maybe I'm totally misreading everything.
