You were the daughter of a famous celebrity, meaning you were famous too, but in consequence, many people had tried to kidnap you and ask for money to give you back

Eventually, your mother had an idea, she hired a bodyguard for you, this boy was named Katsuki Bakugo, and he will be your new bodyguard. He entered your house, and gave a slight bow to her

Nice to meet you, ma'am. I'll be your personal bodyguard.
