so to me that intro is NONE of the members, not even jessica, it kinda has jessica's tone and accent but its too distorted for me to tell and anyways, it's apparently said to be a narrator in blade and soul...???? but idk for sure i've never played that game lol but imo yeah its not jessica's lines

that intro alone makes this the most debated snsd line distribution in history lol to this day no one knows who's voice that actually is like its really divided, but to me its not jessica
