Tiffany began, "We didn't have time to eat because of our busy tour schedule, appearing on various programs, and such. One time, Sooyoung was eating a hamburger and I asked for a bite. I had full makeup on at the time so I smeared lipstick on the burger. When she saw what I did, Sooyoung said, 'If you're gonna eat it, do you mind not putting lipstick all over it?'"
Sooyoung defended herself, saying, "No, I only said, 'Oh, lipstick'. I tend to get very sensitive when it comes to food, and I think Tiffany might have been upset."
Sooyoung went on, "Taeyeon then offered a bite of her hamburger, as if she didn't care about getting lipstick on her food. So then it got a little awkward. It was about five years ago, but Tiffany still acts cautiously when we're eating. [She's] Afraid that she might make lipstick marks!"
