On the October 12 episode of MBC every1′s Weekly Idol, SHINee appeared as guests.During the episode, MC Jeong Hyeong Don and MC Defconn showed a video of SNSD Yoona′s aegyo and challenged SHINee to copy her.
SHINee members strongly opposed, so they decided to choose one member as a representative. After a rock, paper and scissor match, Onew was selected as the representative.
Onew completed the first aegyo mission, but Jeong Hyeong Don was not pleased. After some coaching by Jeong Hyeong Don, Onew tried one more time and was able to perfect his aegyo.
