B1A4 Jin Young and Sandeul, what have you experienced in the dressing room as much as 5 times in a row?

* Correct answer : Felt like being tied up and can't move

* Not just one person but two people ended up taking turns to experience

*At the 5th time, when I opened my eyes a little, I saw the ghostly figure mirroring suffering Jin Young

* Since then we call it "Mr.Spirit" rather than "ghost"
