Place it at the start of a scene as the character introduction, then follow it with a reaction sound once the entrance lands. For a slower build, put a time-passage cue before it, then let this clip open the next scene.
About this sound
This is a short Korean voice clip built around the name Jeon Du Gwang, lasting about four seconds and delivered as a single spoken line. It feels abrupt and dramatic, like a name being called out to stop a room and turn every head at once. That sudden, commanding tone makes it easy to recognise even on a first listen.
