Group Tiara member Hyomin released Ko So-young and two shots. Hyomin wrote on April 4, "Soyoung's new space. Space and dishes can not be so harmonious." The photos released together showed Hyomin visiting a tableware brand event venue where Ko So-young is working as an ambassador. Above all, Ko So-young, who has left Hyomin and a friendly two shot, is amazed by her sister-like visuals despite her 17-year-old age.
