This guy is like a ghost

This video likely worked because it uses a popular movie scene with recognizable actors and a romantic/flirtatious interaction, combined with relatable on-screen text that hints at a narrative.

Two women are on a scenic overlook, one of them spots a man she recognizes from a previous encounter. She approaches him, and they have a brief, flirtatious conversation before she is called away by her friend as their bus is leaving.
