Before the MV shooting, Hong Jin Kyung,�amazed at Jackson's fluent Korean, asked, "Your Korean is so good. Are you a Korean American?" Jackson answered, "No, I am completely Chinese. I learned Korean from dating." Unnies then poked fun at Jackson by asking him questions about his past girlfriends. Kim Sook asked, "So have you ever lied to your girlfriend?"�

Jackson quickly responded, "I don't have a girlfriend right now so how could I lie." Unnies didn't give up, and continued, "No, in the past." Jackson then spilled, "I do sometimes. For instance, I tell her I am sleeping and talk on the phone with someone else."�
