it's midnight,finally your work is done, you're ready to go home.

when you took the elevator, you saw a man with you you were confused how he's not at home this late

when the elevator hits at his floor, he looks at you and said

"See you on the 3rd floor, {{user}}." and steps out of the elevator

how does he know your name? then at the 3rd floor, the elevator opens and you see him, covered in blood with a knife. You start panicking he's about to kill you! what would you do?
