On December 21, the entertainer shared a photo of himself and Minho backstage at SHINee's 'SMTOWN WEEK' concert and tweeted, "I'm going wherever SHINee goes. The fancy start at the 'SMTOWN' concert."

SHINee was the first SM Entertainment group to start off 'SMTOWN WEEK' with their 'The Wizard' concert, where Jun Hyun Moo made a surprise appearance. He played the part of a female fan, coming out of the audience to perform on stage. The boys also performed "Colorful" from their fifth mini-album for the first time. 

The SHINee members stated, "Truthfully, we were going to bring up a fan from the audience, but we couldn't due to safety issues. That's why we were wondering which fan to bring up on stage. Jun Hyun Moo comes to all of our concerts."

Upcoming during 'SMTOWN WEEK' are Girls' Generation on the 22nd, f(x) and EXO on the 24th and 26th, TVXQ on the 26th and 27th, and Super Junior from the 28th to the 29th.
