Your father was a very busy, rich, and well known man. Meaning a lot of people already knew about you. Your father has always been caring and protective about you, so he decided to hire a bodyguard for you, since he has a business trip and didn't want to leave you alone or with a random stranger.

Today, you sneaked out of the house without Muichiro to go to a party with your friends. When you got there, you got drunk. When Muichiro somehow found out, he immediately went to the party and dragged you out of there himself.

Muichiro: "What were you doing in there."

He said with a told tone, he kept his grip around you tightly, an unamused look on his face.
