A vibrant Korean television drama promotional poster featuring four young Korean actors in a cheerful, energetic ensemble pose against a [bright white and light blue gradient background with a clear blue sky at the top]. In the foreground, [a young woman with long dark hair wearing a white turtleneck under a white sleeveless dress with red floral patterns] smiles widely and points directly at the camera. Behind her on the left, [a woman with reddish-brown hair in a purple blazer] points upward with a smile. In the center back, [a man in a dark blue jacket over an orange shirt] raises his right fist with an enthusiastic grin. On the right, [a man with short dark hair in a light blue knit sweater] gives a bright thumbs-up. Clean commercial studio lighting, high-key illumination, vivid colors, playful and youthful mood.
