While many hc that mic is a crybaby, i think its just the opposite.
He never cries. Never. Not even alone.
Why? Because of his quirk- crying and sobbing is an easy way to lose control of your voice, after all, and when your voice is a highly destructive power, its best to stay in control. Mic can handle a little bit of silent tears, but nothing more- not without quirk suppressants (which ngl im not sure if they exist- eris temporary quirk erasing bullets are the closest thing to a suppressant that we've seen in canon).
So question is: does mic only allow himself to cry in front of aizawa?
I dont think he does- we've seen aizawa cry in canon on multiple occasions, but we've never seen mic cry, even after Oboro died. And speaking if Oboro's death, I dont think that aizawa would (in mics mind) appreciate the knowledge that one of the quirks that was used to kill a friend is so easy to lose control of- so I doubt aizawa is even aware that mic doesnt allow himself to cry- and if you hc that aizawa cut mic off after hs, then I think it would be even harder for mic to ask aizawa for help later on.
So I dont think mic cries. I think he would like to, and probably is frustrated with himself about it, but I think he, for the most part, locks away his feelings and lets them stew in his chest, turning from grief with no relief into constant anger, ready to be released upon the barest hint of annoyance.
And I think that his best friend, the only one who could help him, doesn't know, because as much as we'd like to believe aizawa is the emotionally distant one, I think mics true emotions are under six feet of fake smiles and repression. I think mic fears that he would be rejected if he did try to share his grief with aizawa, and I think thats a big part of why he helps aizawa with his mourning, but doesn't mourn much himself- he can mourn through aizawa, and in that way they can mourn together.
