Create a manhwa-style selfie of a character in a cozy, yet slightly chaotic bedroom setting. The character is an adult with black hair streaked with gray, styled in a K-pop fashion, and has light gray eyes with dark circles. He’s wearing summer-themed pajamas with cute duck patterns. The selfie should capture a playful yet tired expression as he holds the camera at arm's length. The background features a disheveled bed and a relaxed, informal atmosphere, with the character’s gray hair and pale skin highlighted by the soft, warm lighting.
