On February 5, he said, "She was a woman with a feminine appearance and good personality like Choi Jung Won.  However, I couldn't get into contact with her well.  I could wait around three hours, but it gradually got more severe to the point I couldn't get into contact with her for about three months.  I was really angry.

She contacted me after three months, so I told her, 'Tell me the truth, please,' to which she said, 'I didn't contact you for three months because I was having concerns about you.'  It was a plot twist.  I tried to get back on her good side."

Who do you think the actress might have been?
