Korean couple self-portrait on shopping mall escalator with realistic Instagram style

[Subject] 
Around 22-year-old young Korean couple, realistic close-up couple selfie on an indoor mall escalator, Instagram Story style.

[Core Pose]
- On the left side of the frame is a Korean woman in her twenties, leaning intimately against her boyfriend.
- Her cheek gently rests on the shoulder of her boyfriend's black loose hoodie.
- She looks up at her boyfriend's face, with an affectionate, trusting, and natural gaze.
- She does not look at the camera, her lips are slightly parted, as if in the middle of a conversation.
- The boyfriend only partially appears on the leftmost side of the frame: the shoulder and chest of the black hoodie occupy the left side of the screen.
- The boyfriend only shows a bit of neck and jawline; his face is completely cropped out of the frame.
- The boyfriend's presence is intimate and close, but he is not the main subject of the picture.
- The woman has natural dark brown hair, loose bangs, and a few strands of realistic messy hair in front of her forehead.
- The woman's skin texture is realistic, with soft blush, hydrated eyes, natural light makeup, and a warm everyday expression.
- The woman is wearing an off-white thin-strap camisole, with realistic stretch textures and a soft feel.
- The woman's body proportions are natural and adult-like, with soft and realistic curves, not exaggerated.
- Only one of the woman's hands appears in the frame.
- Her hand gently grasps the boyfriend's hoodie near the chest area.
- The fingers are relaxed, the anatomical structure is correct, and the wrist and cuff are clearly connected to the arm.
- No hands appear near the woman's cheek or face.

[Environment] 
Indoor mall escalator scene, with blurred escalator handrails, mall ceiling, warm white LED lighting, and indoor spatial structures in the background. The environment is realistic and lifelike, not like a set or a studio.

[Composition Requirements] 
Vertical screen 9:16, smartphone Instagram Story screenshot ratio. Close-up front-camera selfie composition, the woman's face occupies most of the frame, and the boyfriend's body part is naturally cropped on the far left. 
Natural presentation within the frame: the woman's profile and looking-up expression, the boyfriend's black hoodie shoulder, the woman's off-white knit top, the only hand grasping the hoodie, the escalator background and mall lighting. 
The composition should have a slight sense of imperfection, like a private everyday moment captured by chance while the escalator is moving, not perfectly centered, not intentionally posed, and not professional photography composition.

[Camera/Technical Parameters] 
iPhone native front camera image quality, realistic smartphone selfie, slight wide-angle close-up perspective, mobile HDR processing, image quality after social network compression, slight motion blur. The subject is relatively clear, and the background is slightly blurred. Retain real skin texture, pores, details, and natural imperfections; do not over-smooth the skin.

[Atmosphere/Lighting] 
Mall indoor warm white LED lighting, with slight HDR overexposure at the lights. There are soft highlights on the woman's hair, and the boyfriend's black hoodie is slightly dark. Overall atmosphere is intimate, natural, warm, and everyday, like a real private couple selfie rather than a dramatic romantic masterpiece.

[Style] 
Realistic mobile life snapshot, iPhone front camera selfie style, Instagram Story screenshot feel, slightly compressed image quality, natural, intimate, lifelike, non-commercial shoot, non-studio feel.

Extra arms, third arm, repeated hands, second visible hand, hand touching the cheek, hands appearing near the face, floating hands, disconnected arms, distorted wrists, unnatural elbows, deformed anatomy, extra fingers, webbed fingers, incorrect number of fingers, looking at the camera, boyfriend's face showing, professional lighting, studio feel, gorgeous photography, perfect pose, over-retouched skin, plastic-like AI skin texture, anime face, celebrity look-alike face, dramatic romantic scenes, compositions that only crop body parts, sexualized compositions, exaggerated curves, low resolution, heavy noise, severe overexposure, cartoon style, oil painting style, AI feel.
