Split in manhwa

horror movie poster, Korean manhwa/webtoon art style, psychological thriller theme. Centered in a dramatic vertical composition, a fair-skinned woman with long white hair, strands drenched in subtle blood, stares intensely into a large, intricately shattered mirror. Her face shows a neutral, haunting expression with wide eyes and parted lips. The mirror's left shard reflects her heroic expression with soft lighting and gentle smile; the right shard shows her malevolent villainess smirk under harsh shadows. Cracked glass fragments scatter across the mirror surface and floor. Set in a dark, tiled bathroom with eerie backlighting from behind, creating high contrast and rim light. The title space is reserved at the top, tagline space at the bottom. Highly detailed with 8K resolution, sharp focus, clean inks, cel shading, noir atmosphere, atmospheric fog, cinematic lighting, professional illustration masterpiece.
