Korean girlfriend video call screenshot vibe

9:16, direct output from phone front camera, Korean girlfriend perspective video call screenshot vibe in a dark room, cold blue screen light, low light shadow noise, slight out of focus, realistic phone night front camera texture. Adult young female, clear cream nude makeup cold tone variant, thin foundation with almost no concealer, light red bean paste lips, natural semi-matte skin, realistic pores and fine hair strands, black long straight hair flowing, one side tucked behind the ear. Wearing deep grey oversized hoodie, wearing deep grey-black soft top baseball cap, white wired earphones hanging in front of the chest. Arm-length selfie, slightly low angle, face takes up most of the frame, body slightly turned towards the camera, one hand hidden in a wide sleeve propping up the cheek, quietly looking at the camera, expression slightly sleepy, slightly dazed. The only primary light source is the phone screen at the bottom of the frame, cold blue light illuminating the jaw, base of the nose, cheeks and eye sockets from the bottom up, inner side of the cap brim darkened, eyes with small square screen reflections; background is nearly pitch black, only vaguely visible headboard outline. Artistic handwritten signature “ChenLin” in the bottom right corner. No second person, no another face in the screen, no plastic skin, no wet glossy waxiness, no over-sharpening, no additional text watermarks.
