It was fun, but I have REALLY hard time trying to imagine Yuuko even trying to date a guy.
She has like 3 girl crushes just during her high school years... Two of which are definitely queer themselves (Kaoru and Mizore), and Natsuki probably is as well.
What's the Mizore connection? Something in the original novel?
It's in the second season of anime. When Mizore is not getting along with Nozomi, Yuuko tries really hard to befriend her and get as close as she can. Eventually Yuuko ends up having a very emotional scene involving Mizore's connection to Nozomi and the depressive state she is in over it, because she just can't act as a replacement and it frustrates her.
