CAMERA/LOOK: DV 16mm tape camcorder POV, handheld/propped shots. Shaky framing, imperfect focus, clumsy zooms, occasional face cut-offs. Soft blurry tape quality, faint noise, bloomed gym lights, flickering exposure, muted contrast, realistic skin tones. Camcorder never visible. STYLE: Playful, self-deprecating gym vlog. Genuine strain, humor, quick energetic cuts, lighthearted rather than exhausted. CHARACTER: CHASE, Korean idol in her 20s. Long black high ponytail, glowing slightly sweaty skin, expressive eyes, slim athletic build. Modest long-sleeve athletic top, joggers/leggings, socks, no jewelry. SETTING: Evening gym mat area, nearby mirrors, water bottle on floor, soft overhead lighting, equipment in background. 15s / 6 CUTS: 1. (~2.5s) Propped medium shot. CHASE lies on mat, propped on elbows, sighing dramatically. "Okay, core day — my least favorite day." 2. (~2.5s) Plank, slight arm shaking, strained expression. "Why does this get harder every single time—" 3. (~2.5s) Crunches, breathing hard and complaining between reps. "Nobody warns you how much this actually burns." 4. (~2s) Macro close-up, shallow DOF. Hands grip mat during leg raises, abs visibly working. No dialogue, gym ambience. 5. (~2.5s) Handheld/propped shot. Finishes leg raises, flops onto mat laughing. "Okay— that's it, I'm done—" 6. (~3s) Arm's-length selfie while lying on mat, tired grin. "Core day never gets easier — see you guys tomorrow, hopefully."

镜头/画面：DV 16mm 磁带摄像机视角，手持/支撑拍摄。画面抖动、对焦不准、笨拙的变焦、偶尔切掉半张脸。柔和模糊的磁带画质，淡淡的噪点，健身房灯光晕开，曝光闪烁，对比度柔和，皮肤肤色真实。摄像机不可出现在画面中。 风格：俏皮、自嘲的健身房 vlog。有真实的吃力感、幽默感，剪辑明快有活力，整体轻松而非疲惫。 角色：CHASE，二十多岁的韩国偶像。黑色长发高马尾，皮肤微微出汗发亮，眼神有表现力，身材纤细健美。穿着朴素的长袖运动上衣，搭配束脚裤/紧身裤和袜子，不佩戴任何首饰。 场景：傍晚的健身房垫子区域，附近有镜子，地上放着水瓶，柔和的顶部照明，背景中可见器械。 15秒 / 6 个镜头： 1.（约2.5秒）支撑式中景。CHASE 躺在垫子上，用肘部撑起上身，夸张地叹气。 "Okay, core day — my least favorite day." 2.（约2.5秒）平板支撑，手臂轻微颤抖，一脸紧绷。 "Why does this get harder every single time—" 3.（约2.5秒）仰卧起坐，呼吸急促，在间隙抱怨。 "Nobody warns you how much this actually burns." 4.（约2秒）微距特写，浅景深。抬腿时双手抓住垫子，腹部明显在发力。无对白，只有健身房环境音。 5.（约2.5秒）手持/支撑式镜头。完成抬腿后笑着瘫倒在垫子上。 "Okay— that's it, I'm done—" 6.（约3秒）躺在垫子上举起手臂自拍，露出疲惫的笑容。 "Core day never gets easier — see you guys tomorrow, hopefully."
