Actress Moon So-ri, born in 1974, revealed that she is a passionate fan of K-pop rookie group CORTIS. After praising the group's stage performance during her acceptance speech at the 2025 AAA Awards, she recently disclosed her unexpected deep affection for them in an interview. Moon So-ri recalled her first encounter with CORTIS's live performance, saying she was so excited that she almost jumped out of her seat and asked the person next to her "Who are these kids?" She was deeply impressed after meeting the members backstage, amazed by their young age, exceptional talent, and respectful demeanor. The youngest member was born in 2010. Recently, like other K-pop fans, she attempted to purchase concert tickets but missed the pre-registration deadline due to filming schedules. Despite this, she tried her luck during the general sales period with help from company staff. Moon So-ri also revealed that she frequently listens to CORTIS's music in her daily life, playing their songs during makeup sessions and photo shoots to boost her energy. She concluded by encouraging the group, saying "This album is heading in unexpected directions and is even more interesting," and expressing hope that "you will continue to present music that exceeds fans' expectations and keep making bold challenges with your youth."
