Vertical 9:16 ultra-realistic casual iPhone selfie of an adult East Asian woman in her twenties, delicate oval face, narrow almond eyes, soft youthful features, long slightly messy black hair with loose strands, fair natural skin, peach-pink blush, nude-pink lips. She wears a fitted black thin-strap camisole, large gold hoop earrings, and a delicate gold open-heart necklace. Sitting casually in a cozy bedroom beside a bright window, holding the phone at arm's length, upper body slightly angled, gentle head tilt, soft eye contact, relaxed parted lips. Natural window light, slightly overexposed skin highlights, realistic pores and flyaway hair, mild wide-angle distortion, subtle grain, low contrast, warm hazy iPhone snapshot aesthetic. A small glowing amber timestamp appears vertically near the bottom-left: "26年 8月27日".
