K-Pop 偶像健身房对镜自拍

A realistic medium shot in a gym with mirrored walls featuring Karina and Winter from aespa. On the left, Karina has a sharp, AI-like visual with a slender physique and pale fair skin, her dark blue-black hair tied in a ponytail, wearing a white Alo Yoga ribbed sports bra and biker shorts set, smiling while looking down with minimal makeup. On the right, Winter has a petite, toned body and very fair skin, her bob-cut blonde hair pinned back in a messy bun, distinct soft features, wearing a royal blue deep V-neck sports bra and shorts set, smiling at her phone while taking a mirror selfie. The background is filled with weight racks, benches, and gym equipment, illuminated by bright overhead LED strips. --ar 9:16
