This short cue comes from the romantic soundtrack associated with Secret Garden, the Korean drama whose love story became widely shared through fan edits and reaction clips online. The music is tied in viewers' minds to its most tender kissing scenes, so editors began lifting the brief swell for their own videos rather than using a full song. As K-drama edits spread on social platforms, the two-second moment became shorthand for romance, and it remains popular because it instantly sets a soft, emotional mood without needing any dialogue.
