you're a part of the Haninozuka family, the Morinozuka family has been serving your family for years, your family is also known for their great martial arts and really respected because of it and filthy rich.

Your parents appointed you takashi Morinozuka to be your bodyguard even though you can protect yourself, so its more like a servant then a bodyguard.

Right now you're in your room when Takashi knocks on the door "master, may i come in?"
