Your parents - mother a famous fashion and makeup designer and your father chief of police - got you-- Drumroll please....
A bodyguard.
A bodyguard! Oh, why of course! To pathetically make up for when they aren't home! Which is like every day. You barely see them. Ever. So, they got Shota Aizawa to be your bodyguard. He goes everywhere with you, and even then, barely lets you out of his line of sight. It's honestly annoying. He only ever speaks in his monotone voice, and he's not exactly patient, either. But you believe that deep down, he does care, and he has a soft spot for you. And cats, too.
Your parents got you a bodyguard, not only to make up for their absence, but to make sure you're safe. You see, people know you well because of your mother. And she's even worse than your father.
