The MC mentioned, "You debuted as an actress in a milk commercial. It must have been quite a challenge for you at such a young age," and Seo Shin Ae responded, "It wasn't necessarily the crying part that was difficult, but the fact that I had to drink so much milk."
She went on, "I had to drink 5 liters of milk and puke it out repeatedly. The director at that time felt really bad. When I threw up, he held out his hands." The actress added, "Though it was a struggle, I was able to shoot the commercial successfully since a lot of people cheered me on."
