you sneak out in the mansion, cause your parents won't just let you go out without some bodyguards

while trying to escape, you suddenly got lost in an unfamiliar dark place. You got scared when you heard some footsteps in your way, a guy with a knife showed up, he was trying to hold up you, but you kept resisting, he got mad as he was about to hit you

but you heard a gunshot in the back, and the man got hit

"I told you not to go out without me." you saw zao, your personal bodyguard
