A 15-second vertical-screen lighthearted slice-of-life comedy short film. Set in the elevator lobby

A 15-second vertical-screen lighthearted slice-of-life comedy short film. Set in the elevator lobby of an ordinary apartment building in South Korea at dusk, featuring warm white hallway lighting, beige tiled walls, metal elevator doors, floor buttons, a bulletin board, a fire door, and a few delivery boxes in the corner. The setting is ordinary and clean, but not luxurious. It has the authentic look of a casual smartphone video: slight handheld shake, imperfect framing, auto-exposure that fluctuates slightly with the hallway lighting, and authentic ambient sound. No cinematic style, no polished commercial look, and no subtitles or text overlays. Main Character: An adult Korean woman in her early 20s, wearing natural, light makeup with a realistic skin texture. She has a low bun with a few strands of hair falling loosely. She is wearing a loose, light yellow loungewear sweatshirt, gray plaid pajama pants, white cotton socks, and beige house slippers. She holds a cell phone in her right hand and carries a small trash bag in her left. She maintains the same facial expression, hairstyle, outfit, and held object throughout the entire scene. Supporting Character: A neighbor, a middle-aged woman in her 50s, wearing casual outdoor clothes. She stands in the corner of the elevator, showing only subtle facial reactions; she does not deliver long lines and does not approach the protagonist. Key Event: She has just rushed out of her apartment to go downstairs and pick up her takeout, nearly missing the elevator; after catching it, she discovers a small white sticker stuck to the side of her pajama pants, which the neighbor notices. Embarrassed, she tears off the sticker and pretends nonchalantly to stuff it into the trash bag, but can’t help but chuckle as the elevator doors close. 00:00–00:02 The shot begins at the edge of a half-open apartment door. The protagonist walks briskly into the frame from the right, looking down at a takeout notification on her phone while holding a small trash bag in her left hand. Her slippers make a soft tapping sound on the tile floor. Before she has fully looked up, the warm white light of the elevator lobby illuminates a sense of everyday life. The camera angle is slightly tilted, as if a friend were casually filming from the hallway. 00:02-00:04 The elevator doors on the left side of the frame are about to close. She suddenly looks up, her eyes wide, and takes two quick steps, reaching out to press the outside button. The camera is a split second behind, first capturing her slippers and the swaying trash bag, then panning up to her panicked face. Her movements are small; she isn’t really running. 00:04-00:06 Her finger presses the elevator button; the button lights up, and the elevator doors pause before reopening. Her shoulders visibly relax; she exhales, a hint of smug satisfaction—as if to say, “I made it”—flashing across her lips. Inside the elevator, a neighbor stands in the back corner, quietly watching her. The elevator doors reopen only once. 00:06-00:08 Just as she steps into the elevator, the neighbor’s gaze falls on the side of her pajama pants. The protagonist follows the gaze and looks down, discovering a small white sticker stuck to the side of her gray plaid pajama pants, with one corner slightly curled up. Her expression shifts from relaxed to frozen, her mouth frozen in a half-smile. The sticker should not display any legible text; it should simply be a small white sticker or a blurred QR code-like image. 00:08-00:10 Close-up of the protagonist, with a slight zoom-in. Embarrassed, she presses her phone against her chest, steadying the trash bag with the hand holding it while quickly peeling the sticker off the side of her pajama pants with her other hand. Once done, she holds the sticker between her fingertips, and her pants are smooth again. She furrows her brow to suppress a laugh, her gaze briefly drifting toward the camera. Avoid prolonged close-ups of her fingers tearing the sticker. 00:10-00:12 Medium shot with two people in frame. The protagonist crumples the sticker into a small ball and pretends to casually stuff it into the trash bag. She nods and smiles at her neighbor, who politely looks away but can’t quite hide the faint smile playing at the corners of her mouth. The protagonist tries hard to maintain her composure, her eyes seeming to say, “Don’t ask.” 00:12–00:15 The protagonist steps into the elevator and stands in place, holding both her phone and the trash bag. The elevator doors close slowly. As the gap narrows, she finally can’t hold it in any longer; she looks down, covers her mouth, and giggles. The doors close completely, and the shot lingers on the metal doors and floor buttons, ending naturally. Action Guidelines: Only one core action per segment; the elevator door’s status must be clear: closing, paused by a button and reopening, then closing completely; the sticker is placed only on the side of the pajama pants—not on the face or hands; the cell phone and trash bag remain steady in her hands at all times; the neighbor only reacts with a slight effort to suppress a laugh; do not add a delivery person, a takeout bag, or any other props. Audio: Authentic apartment hallway sounds. The sound of slippers on tile floors, slight rustling of the trash bag, phone vibrations, the “beep” of the elevator buttons, the mechanical opening and closing of the elevator doors, and low-frequency echoes in the hallway. The protagonist’s short, sharp breaths and an awkward chuckle; the neighbor very softly clears her throat or stifles a laugh. No music, no narration, no subtitles. Restrictions: Realism and believability take precedence over visual appeal; no luxury apartments; no mall elevators; no exaggerated falls; no over-the-top acting; no garbled text; no brand logos; no deformed fingers; no face-swaps; no clearly legible text on stickers; no supporting characters stealing the spotlight.
