Despite the excitement surrounding collaborative performances, many netizens have voiced their concerns regarding the potential for suggestive choreography and the age disparity between Yoonchae and Yeonjun. Even though Yoonchae just celebrated her 18th birthday, critics argue that she is still a minor in South Korea, raising questions about the appropriateness of her involvement in such a concept.
