Not the same.

PerfectAll-Kill is also referred to as "PAK" by fans, which refers to the song's real-time rankings and daily rankings on mainstream Korean music websites (MelOn, Genie, FLO, VIBE, Bugs, Soribada, etc.) Topping the charts and weekly charts can be said to be the achievement that Korean musicians most want to achieve. PK (PERFECTKILL) is based on AK, and getting one place on the weekly list is PK.
