Well, this is very silly question, btw.
Just read Akira's past in chapter'Caged Bert' and it's clear that her father is typical weak-willed cuck while her mother is waste-of-the-oxygen whore and cheater.
My said silly question: why it is set like that? I mean, why not the vice versa where both of them are cheaters or the personality is reversed?
Sorry for the silly question. Just wonder the lack of story about cheating man and weak-willed woman.
