[ASKKPOP] The next BTS member gets ready to board the 'Sick' elevator

We got the full hyung-line already withJinjoiningRap Monster,Suga, andJ-Hopein the elevator, so the only ones left are the maknae-line. There have been various speculations as to the order the images are being released. There are also theories on the concept being that the boys are headed to help someone, as Rap Monster is a bell boy, Suga is a 911 emergency response personnel, Jin is a doctor, and J-Hope is... some sort of biker in a suit.

With this 5th member, the elevator seems like it's going to get quite crowded. Who do you think this could be?V?Jimin?Jungkook?
