During the filming, daughter Kim Shin Young played a speed quiz over the phone with her mother, who captivated cast members with her elegant voice. Kim Shin Young's mother managed to cause laughter among the cast as she maintained her poise even when she gave the wrong answer. The audience laughed especially when the mother said "I knew" for one of Seo Tae Ji's songs when the real answer was "Moai." Apparently, the mother was thinking of Seo Tae Ji's classic song "I Know" but mistakenly said "I Knew" instead. Additionally, Kim Shin Young's mother left an endearing message for her daughter. "I wish she just continues being who she is now. I don't think there is any child who is as pretty as Shin Young," expressing a mother's love for her daughter.
