The one who appears to be tough and everyone is afraid of him or does not approach him and keeps away from the rest, but one day he meets someone who changes him and makes him magically sociable and surrounded by friends and love (who would not want to live something like that haha 😂)
I think he would be catalogued as the antisocial one.
So Tsundere?
I didn't remember the term, but yeah 😂
That reminded me of Kenpachi from Bleach 😂
