Um..Bakugou?

My AU
They are now in class 2-A
Halfway through 1-A everybody slowly noticed that bakugou became quieter and acted nicer?!..Then they started to notice bruises and scars. When they came back from summer break(they are now in class one like when your in one grade then there is a break and now your in another grade like that break thing ok yeah whatever) They instantly noticed Bakugous face scar (like kakashi's) and that the eye whith the scar was white?!(he is now blind in that eye) they also noticed that he had snakebite piercings and a tattoo on his hand?!(a snake)

All they could wonder was..
