ITZY’s Yuna has reportedly been cast in a leading role in the series and will star as transfer student Kim Lizzy/Kim Ri Ji. The majority of her television appearances have been as herself on various variety and talk shows, but she did make her acting debut in 2026 with a guest role in Undercover Miss Hong, where she played Geum Bo’s younger sister, Hong Jang Mi. Yuna will also be starring in a supporting role in tvN’s upcoming romantic comedy My Bias, My Boss.
The character of Kim Lizzy/Kim Ri Ji has been described as:
“A transfer student at Jinwol Girls’ High School and a love supremacist. With her unique vibe and cute face, she entered Jinwol Girls’ High School—known for its strict transfer requirements—as a long-distance specialist on the track and field team. Once she had somewhat adapted, she began telling stories about her
previous co-ed school to attract the attention of female students and boasted about the phone numbers of male students, causing cracks to gradually appear in the class atmosphere, which had previously been excellent for studying.”
