公園のスイカ、黄色いキャミ

Candid vertical smartphone snapshot of a cute adult Japanese woman in her early twenties (unambiguously 20+ adult, fictional OC), kawaii-beautiful Japanese face: bright eyes, soft cheeks, playful half-smile mid-bite, black hair in twin low loose pigtails with slight humidity frizz, summer sun on cheeks. Outdoor summer park picnic on a blue vinyl sheet under dappled tree shade, holding a triangular slice of bright red watermelon with a green rind; juice on lips/fingers. Wearing a simple yellow sleeveless summer top and denim short-shorts; natural breast volume through soft fabric, casual cute, no nudity. Lived-in picnic clutter: plastic bags, paper cups, cooler corner, grass and dirt, harsh summer backlight. Real iPhone candid: uneven exposure, natural phone color, pores and real skin (not beauty-filter plastic), imperfect crop, eyes slightly off-lens. Portrait 9:16, single subject, SNS-postable unpolished summer. No watermarks, no heavy gibberish overlays, no extra limbs.
