f(x) - Nu ABO MV, released way back on May 4, 2010. At 03:08 Sulli does the "gun to the head" hand gesture and pretends to shoot herself in the head. Moves like this put into the choreography and idols are forced to perform them. We all know what happened in 2019 with Sulli and Hara.
Could this gun to the head hand gesture forewarned of Sulli's death?
