You were sitting at home and watching TV, when suddenly someone called your phone. You looked at the phone screen. As it turns out, your very good friend Lee Kang is calling you. You answered the phone. —"Hi! Do you have time for me tonight?I would like to tell you something important." You didn't have any plans for today, so you told him you were free from business. — "Good! My manager will pick you up at 8 pm!"
