[Style]

A realistic short video of a cinematic birthday party.

[Duration/Aspect Size]

15 seconds, 9:16 vertical screen. 

[Scene]

Birthday party scenes in indoor restaurants or bars. 

The female lead sits behind the table, with a delicate round birthday cake placed in the center. The background features a dark wine cabinet, wine bottle displays, and warm yellow circular lighting. The environment is dim, and the figures and cake are illuminated by soft, warm light. 

The positions of the table, cake, seats, background lighting, and wine cabinet remain stable throughout, without altering the scene structure. 

[Core Items]

Silver birthday crown, round birthday cake, slender white curved birthday candle, lighter. 

From presenting, lighting at the mouth, removing to inserting the cake, the same candle must always be used, and its length, color, curved shape, and appearance must not be changed midway. 

[Camera and Composition]

The camera is fixed directly in front of the female lead, with the lens about 1.4 meters away from her face, maintaining a stable mid-shot front. 

The footage fully captures the female lead's head, face, shoulders, upper body, hand movement areas, the tabletop, and the complete birthday cake, while retaining part of the background wine cabinet and warm lighting. 

Throughout, there is no shaking of the lens, no tilting or tilting, no lateral movement, no pushing or pulling, no backward, no zooming. Changes in the person's distance can only come from the female lead's natural forward tilt or return to straight; the camera cannot create changes in shot angle. 

The first seven shots are completed consecutively in the same fixed frame and composition; Shot 8 uses the current frame of the fiery climax in black and white. 

[Scene 1: Wearing the birthday crown]

At the start, the female lead is already seated behind the table, with the birthday cake steadily placed in the center of the table. 

A hand reaches into the upper left of the frame, placing the silver birthday crown on the heroine's head and naturally adjusts it to a stable position. 

The female lead first observes the hand wearing the crown with her eyes, then looks forward again. She maintains a calm and natural expression, with only slight blinks and changes in breathing, avoiding an exaggerated smile at the start. 

The crown must be worn by an off-screen character; it cannot be worn at the beginning, nor can the female lead pick up the crown herself. 

[Scene 2: Holding a birthday candle like a cigarette]

On the right side of the image, a hand is reached, holding a slender white curved birthday candle, which is placed horizontally to the female lead's mouth. 

The female lead remains seated, her head basically facing the camera. She naturally opens her mouth, holding the end of the candle close to her body between her lips, while the other end extends outward. 

The female lead simultaneously raises her right hand, using her index and middle fingers to hold the candle at the corner of her mouth, her hand gesture as if holding a cigarette to wait to light it. 

The sequence of actions must be clear: 

Hands in the candle on the right side
→ The candle is placed horizontally near the female lead's mouth
→ The female lead holds one end of the candle in her mouth
→ The female lead holds the candle at the corner of her mouth with her index and middle fingers
→ Release the hand holding the candle and exit the frame. 

At this time, the candle must be kept horizontally or slightly tilted, not raised vertically, and not inserted into the cake in advance. 

This is a birthday candle, which only mimics the action of holding a cigarette in its mouth and lighting it. It is forbidden to generate real cigarettes, filters, tobacco, smoke, smoking, or exhaling any content. 

[Scene 3: Lighting a candle at the mouth as if lighting a cigarette]

The female lead continues to hold the slender candle close to her lips, holding it near her lips with her index and middle fingers, maintaining a posture of waiting to be lit. 

On the left side of the frame, another hand is reached, holding a lighter. The lighter moves to the exposed end of the candle away from the female lead's mouth. 

The off-screen figure presses a lighter, a flame appears, and as if lighting a cigarette, brings the flame close to the exposed end of the candle until the birthday candle is successfully lit. 

The sequence of actions must be clear: 
The female lead held the candle in her mouth and held it firmly with two fingers
→ Lighter enters from the left side
→ Move the lighter to the exposed end of the candle
→ Lighter flames appear
→ The flame touches the end of the candle
→ The candle was successfully lit
→ Stable small flames form at the top. 
During the ignition, the female lead maintains a serious, calm, and cooperative expression, naturally observing the lighter and flame near her mouth, creating a subtle contrast. 
A lighter can only light the candle held by the female lead's mouth; it cannot be used directly to light the candle on the cake, nor can it burn her lips, fingers, hair, or face. 
[Scene 4: Remove the same candle that was just lit]

Once the candle is successfully lit, the hand holding the lighter immediately withdraws from the frame. 

The female lead still holds the candle between her index and middle fingers, as if removing a freshly lit cigarette from her mouth, naturally pulling it out between her lips. 

The sequence of actions must be clear: 

A candle is lit at the edge of his mouth
→ Lighter exit screen
→ The female lead's lips parted
→ Hold the candle between your fingers and remove it from your mouth
→ The female lead raises the lit candle to her chest
→ Briefly observe the small flame at the top of the candle
→ Naturally shift your gaze to the cake on the table. 

It must always be the same slender, curved birthday candle. The candle must not jump out, disappear, shorten, straighten, break, or change appearance. 

[Scene 5: Inserting the candle into the cake]

The female lead holds the same lit candle in her right hand and naturally lowers it from her chest onto the top of the cake. 

Fully perform the following actions: 

The candle fell
→ The bottom of the candle touches the top of the cake
→ The female lead inserts a candle into the cake
→ Adjust the candle angle with your fingertip
→ After confirming stability, release your right hand. 
After insertion, the candle remains in its original slender, curved shape, with the top flame continuing to burn normally. 
Candles must not appear out of thin air in the cake, candles must not pierce directly through the cake, and the cake must not collapse, shift, or deform due to insertion actions. 
[Scene 6: Bending over to blow out the candles]
The female lead withdraws her right hand and sits up straight, her hands naturally resting on either side of the table. 
She first looked down at the candle flame on the cake, a natural, restrained smile appearing at the corner of her mouth. Then her upper body began to lean naturally forward toward the cake, her face gradually approaching the candle. 
The sequence of actions must be clear: 

Looking at the candle flame
→ Place both hands on either side of the table
→ The body naturally leans forward toward the cake
→ The face gradually approaches the candle
→ Lips purse and enter a state of preparing to blow out the candle. 

The female lead always faces the cake and the camera, never turning her head left or right. The camera stays fixed, so the figure naturally grows larger in the frame and can only lean forward. 

The candle flame continues to burn steadily and cannot be extinguished prematurely. 

[Scene 7: Suddenly bursting flames while blowing out a candle]

Strictly continuing the previous shot's bent-over candle-blowing pose. 

The female lead faces the cake, purses her lips, and begins to blow air forward like a normal birthday candle. At the moment she officially blows air, instead of blowing out ordinary air, her mouth suddenly emits a real, intense, continuous orange-yellow flame. 

The sequence of actions must be clear: 

Lean your body forward toward the cake
→ looked at the candle
→ Lips pursed
→ Start blowing air
→ Sudden flames appear in the mouth
→ Flames continuously shoot above the cake and in front of the camera
→ The female lead maintains a climax pose bent over and blowing out the candle. 
Flame requirements
The flame can only appear from the center of the heroine's mouth; 
The flame must be triggered by the blowing action and cannot appear prematurely; 
The flame direction must match the direction the female lead blows out the candle; 
Flames shoot out from the mouth straight forward, slightly brushing over the top of the cake; 
You can't expect the female lead to look up and breathe fire, sit upright, or turn left or right to breathe fire; 

It must be continuously fired, not just a brief fireball; 

The center of the flame is bright with a yellowish tint, with an orange-red outer edge; 

Realistic winding, flow, tail flame, and slight heatwave disturbances; 

The firelight naturally illuminates the heroine's face, hair, crown, clothing, tabletop, and cake; 

The cake surface and the table show real warm reflections; 

Flames cannot completely cover the cake, cannot burn it, and must not cause the cake or candles to melt or deform; 
Flames must not distort a person's mouth, teeth, face shape, hair, or facial features. 
The female lead always maintains a candle-blowing posture with both hands on both sides of the table and leaning forward, unable to sit upright, lean back, stand up, or change her posture just because of a flame. 
The cake is always placed steadily in the center of the table, and the bent birthday candle remains stuck in the cake. After the flame appears at the mouth, the small flame on the candle can be covered by strong airflow and flame, but the cake and candle body cannot disappear. 
When breathing fire, the character's expression remains calm and restrained, creating an absurd contrast; there is no fear or ferocity, eye rolling, or excessive force. 

[Scene 8: Black-and-white birthday poster freezes on candles blowing out flames]

When the female lead remains bent over to blow out the candle, her mouth flame reaching the longest, most complete, and most impactful moment, the current frame is used to freeze the black-and-white birthday poster.
