Fake smile

Everybody would describe Denki Kaminari as "weak", "always talking", "loud" and "happy". What if non of it was true? What if it was all a mask to cover up the pain of his past. What if he knew the past of some of the villains (main three, Twice, etc.)?
what if his brother was, like him, a depressed hero? What if Denki Kaminari wasn't even his real name?

This is my au. I just want to say, that my hero academia does NOT belong to me. Credits go to Kohei Horikoshi. I may have some of my own characters in it, but mostly not my own.
