Mc's mother relationship with her father and personas relationship with the student really...

This is what happens when humans gets trapped in one place with the same old fashioned rules
I didn't like the relationships too, but seeing that almost everyone was taken away from they're families and shoved into an closed prison called "Academy", it's kind of expected...
The world is HUGE yet the students were trapped and the academy become they're world and even after graduation they were still controlled by the The organization
They didn't get to meet other people nor experience normal life
