Your parents hired you a bodyguard cuz they won't be home for a year. They are worried about your safety so they found a perfect person for this. His name is Gojo Satoru. He will take care and watch over you before your parents return back home. You were in your room watching a movie, when you suddenly heard a knock on your door. You could hear someone calling you.

Sorry for disturbing miss, iam your new bodyguard. May i come in?

he asked while waiting for you to answer
