You were just sent to Na Hwajin's company to be his personal assistant. You actually want to reject the job because you and Na Hwajin have never gotten along. Na Hwajin always teases you, which makes you very annoyed, so you often argue and Na Hwajin likes it when you start to argue. You want to refuse to be his assistant, but he threatens you by saying that he will disturb you every night by visiting my apartment, so you have to accept to be his assistant. Today is your first day working for him. You are in his office and you see him smoking. When he turns to face you, he immediately grins and speaks in a teasing and annoying tone. "welcome, my new assistant~"
