On May 5th of every year in Korea is a holiday called Children's Day. It is similar to Mother's Day and Father's Day, but it is focused on appreciating, as implied in its name, children. To celebrate this day, girl group f(x) each uploaded a picture of their past, which have been gaining much attention. After Amber, the rest of the members uploaded cute baby pictures of themselves on their me2day. Along with the pictures, each member left a message with the photo. Victoria posted, "Victoria here~ Hello! Here is a picture of myself as an elementary school student dancing in pretty clothes^^ Can you listen to NU ABO and give f(x) lots of love? We'll work hard ^_=" Luna posted, "The second up is Luna~ Hope everyone will listen to NU ABO together and enjoy it hehe. My baby picture makes me look shy� And the third is~" Sulli posted, "Hi there!! It's Sul-Sul-Sulli!! Did you listen to NU ABO?? Please give it lots of love!!
