Birthday Cake Surprise Gone Wrong

STORY: Han Ji-eun (26), wearing a beige wool coat, cream sweater and black skirt, arrives at her boyfriend's Seoul apartment at night, carrying a white birthday cake with lit candles. She expects a romantic surprise. Instead, an unfamiliar woman, Choi Yuna (24), wearing an oversized charcoal-grey men's hoodie and lounge shorts, opens the door.

12-SHOT SEQUENCE:

1. (0–2s) Tracking shot: Ji-eun approaches the apartment, smiling with her birthday cake. 2. (2–4s) She rings the doorbell, fixes her hair and whispers, “생일 축하해 줄게.” 3. (4–6s) Door opens; an unfamiliar woman appears. Ji-eun's smile fades. “누구세요?” 4. (6–8s) Ji-eun asks, “저… 민재 씨 집 맞죠?” The woman casually replies, “네. 그런데요?” 5. (8–11s) The woman claims, “저 민재 오빠 동생인데요.” Ji-eun looks confused. 6. (11–14s) Low-angle reveal: men's shoes beside unfamiliar women's heels. Ji-eun notices. 7. (14–17s) Camera reveals two wine glasses, an open wine bottle and a woman's handbag inside. 8. (17–20s) Ji-eun quietly says, “저… 여자친구인데요.” The woman's smile disappears. 9. (20–22s) Close-up: Ji-eun's trembling hands struggle to steady the tilting cake. 10. (22–25s) A male voice from inside: “누구 왔어?” The woman replies, “오빠, 손님 왔어.” Ji-eun freezes. 11. (25–28s) Min-jae (28), black T-shirt and dark lounge trousers, walks into view, sees Ji-eun and freezes. “지은아…?” 12. (28–30s) Ji-eun looks down at the cake, forces a tiny painful smile and whispers, “생일 축하해…” Cut immediately to black.

CHARACTER LOCK: Ji-eun: Korean, 26, soft oval face, natural skin, expressive dark eyes, long wavy dark-brown hair, beige coat, cream sweater, black skirt, handbag. Yuna: Korean, 24, slightly messy dark hair, bare face, oversized charcoal hoodie, lounge shorts. Min-jae: Korean, 28, neatly styled short black hair, black T-shirt, dark lounge trousers. Maintain identical faces, clothing and proportions throughout.

VISUAL DIRECTION: Premium cinematic K-drama realism, natural Korean performances and accurate Korean lip-sync, expressive micro-reactions, realistic skin and fabric, shallow depth of field, slow tracking and suspenseful push-ins. Warm apartment lighting contrasts with cool corridor lighting. Consistent apartment layout and prop positions. Cake stays in Ji-eun's hands throughout. Min-jae appears only in Shot 11.

AUDIO: Natural Korean dialogue, accurate lip-sync, footsteps, elevator ambience, doorbell, handle movement, faint TV and subtle suspense score that builds toward the reveal, then nearly disappears.

EMOTIONAL ARC: Excitement → confusion → suspicion → humiliation → heartbreak. No confrontation, explanation or resolution. End immediately after “생일 축하해…” with a hard cut to black.
