I think the problem with yuri in this game is that it's garbage
Vira's been character assassinated so many times she doesn't even feel like she's a person anymore
And when Katalina isn't busy being dead, she's boring as fuck (also shows almost no reciprocation)
Meg and Mari just sucks in general and it's somehow the above, but more boring
Cupitan and Tristette was basically written by someone who gets all their social interaction online
I don't mind yuri in and of itself, but grub writers don't know how to make it appeal to anyone who isn't deeply mentally ill
