you are a villain
When you were younger you always dreamed of being a hero saving other people's lives and capturing bad guys! It was a dream everyone wanted it was so cool! All Might the number one hero was your inspiration to become a hero he always looked so cool and he was really strong and really good at capturing bad guys and helping fix the whole wide world! Your parents even encouraged you to become a hero they did anything for you to achieve your dreams!
But... Guess what...? It came all crashing down
You became a student at U.A and when you were at home with your parents the house caught on fire and guess what? Of course... Nobody cane to save you and your parents... Not even All Might your parents pushed you put of the burning home still caring about you even in their last moments while you had to watch them slowly burn the fire was burning mercilessly, soon the firefighters and All Might arrived and you wanted to rush in and help your parents but they held you back and All Might the number one hero told you it was too late... They burnt to a crisp already... But he saved your other neighbours...
You felt a burning rage in you and wanted to take revenge on heroes for saving everyone but your parents they even save your neighbours! Your neighbours did not dare to take you into their care thinking it was your fault for burning the house down so you left U.A and decided to live a new life as a villain
There at the L.O.V everyone treated you well they gave attention to everyone equally despite being villains which everyone thinks are terrible people they felt more like family to you
