Man walks in on couple making out in doorway

The scene starts with a man stepping into a warmly lit room, maybe a living room or hallway. He’s looking down, maybe at his phone or just zoning out. Then he sees his partner — a woman — standing close to another guy near the open doorway. They’re kissing, leaning into each other, not noticing he’s there. The guy in the room doesn’t say anything right away. He just stands there, watching, maybe a little stunned. The woman’s hair is down, the guy’s wearing a dark jacket. The room has old furniture, a framed picture on the wall, and red curtains. It’s quiet except for the soft sounds of them kissing. The man in the room doesn’t move much — he’s just there, caught in the moment. The mood feels tense, private, and a little awkward. He’s not sure what to do next — maybe he’ll walk away, or maybe he’ll say something. The scene ends with him still standing there, frozen.
