But we all know this manga is going to end with Mei getting both, Yuzu AND the Academy (well at least in some form, maybe her father takes over till she is older).
I get the social and cultural stuff (even if it is not as hardcore anymore as it used to be in Japan) but this is still a fictional story and not some hyperrealistic drama. It will end like most boring drama ends, some perfect solution. But what is the most annoying, Mei NEVER tries to fight. She never tries to question her grandfather or anything. She is a submissive slave to his wishes, even if she writes otherwise. Managing the Academy was indoctrinated into her since she was a young child.
This is Yuri-Hime's flagship yuri series. Anything but a 110% happy ending would hurt them. So we can be sure the Editor wont allow any silly stuff like sex with fiance or god forbid another timeskip with her being married.
