Mao Mao's Alone Time

Okay so this fanfic is based of a theory. We all know Mao Mao surprises emotions and traits of himself he considers weak, but what if it was more than that? What is Mao Mao hid an entire part of himself from his friends, a part of himself that still shows the child he was, and still kind of is? What if Mao Mao even hid his very voice? Want to learn more about this theory, then read the fanfic. The cover picture also gave me some ideas. Also there may be some Badgermao shipping in this. I'm a simp for Badgermao.
