While the couple watched the romantic film 'Twilight', the mood quickly turned sour when Taemin asked, "Have you ever kissed another guy? Was it that guy?", and Na Eun revealed, "No, there is another guy. I did it in a drama and music video. But it was edited out. That was my first kiss. I've even got kissed on the cheek. Now that I think about it, there were a lot", fueling Taemin's adorable jealousy.

Taemin wanted to know more and continued to ask, "Your kiss in the music video. Who did you do it with?", to which Na Eun shared, "One of them was an actor. The other is B2ST's Junhyung." 

Taemin responded, "So you did get kissed a lot. Good. Good. You did well, our Na Eun. How many NGs did you have?", Na Eun revealed, "A lot." Taemin asked, "So you kissed a lot?", to which Na Eun nodded her head. Taemin said again, "Good job", trying to cover up his jealousy.

Taemin shared during his interview, "It bugged me. It was just shocking to suddenly hear something that I didn't know before. I will make a confession right here. To be honest, I had a girlfriend in the past, it was in elementary school. I wasn't single my entire life. I even dated one person for a whole week!"
