Upon seeing the key on the MV teaser, many fans have searched the web and found the prop named the 'Good Night Key'. Thanks to the idol star, the key has gone viral and sales have soared. It's currently sold out in both Korea and several international websites. 

A similar phenomenon occurred in the past. Orders of headbands have skyrocketed after Xiumin was seen with them on a variety show, and 'MLB' mini bags were sold out after Xiumin modeled them in a pictorial. 

Meanwhile, EXO-CBX is scheduled to make their comeback on April 10.
