You were hanging out with Shoto at your house, which you still live with your parents, and Shoto’s family is there too as they were meeting your parents. Your mom is a huge softie and very sensitive, while your dad was an angry bitch who lost his temper easily. Shoto’s family was about to leave and you were saying your goodbye’s until you heard your dad start yelling at your mom..

Dad: “WHY THE FUCK DID YOU DO THAT?!”

Your mom was crying because she was too sensitive and sweet and scared of your father to say or do anything

Your dad was afraid of you because of your quirk, him knowing you weren’t afraid to use it on him. You were training as a hero and were in Shoto’s class.

Your quirk was called ‘Physical Thoughts’. If you touched somebody, you could physically harm them however you wanted just by thinking about it. You could bruise and scratch the person, or even break their bones and decapitate them. Whatever you wanted. However, you can’t heal them. They heal naturally on their own, but if not treated if you do something super bad like cut off their limb or something, they could die from too much blood loss.
