Create original characters with this visual language. Avoid childish proportions, huge sparkling eyes, bright frills, and copied recognizable existing comic characters.\nPrimary request: Design BOTH original Chinese protagonists of the Shanghai romance mystery novel 《请替我活到星期五》. Make a beautiful, production-ready illustrated character model sheet with premium adult romance manhua / manhwa aesthetics: fine clean expressive ink lines, elegant anatomically believable faces, clear eyelids and brows, restrained painterly cel shading, luminous natural skin, silky grouped hair strands, tasteful muted colors. This is drawn comic concept art, not photographs, not 3D, not chibi.\nCharacter A: 许知夏 / XU ZHIXIA, adult Chinese woman age 26, 165 cm, practical and resilient with gentle warmth. Slender healthy active build, approximately 7.25 heads tall. Natural oval face, gently rounded chin, almond-shaped dark brown eyes, medium straight expressive brows, small straight nose, natural muted rose lips. Dark espresso-brown medium-long hair reaching just below shoulders when loose, 6:4 side part, tied in a low practical ponytail with short loose strands at the temples. No huge baby eyes, no jewelry.

Small plain dark crossbody phone pouch.\nCharacter B: 陆沉 / LU CHEN, adult Chinese man age 30, 185 cm, quiet protective warmth under emotional restraint, sleep-deprived subtly rather than sick. Slim athletic long-limbed build with broad but natural shoulders, approximately 7.75 heads tall. Softly angular oval face, defined jaw, straight high nose bridge, long narrow dark brown eyes, straight thick brows, restrained mouth. Natural jet black short layered hair with irregular soft fringe and subtle off-center part, NO brown hair, no slicked-back style, no glasses, no facial hair, no earrings or tattoos.

Real adult masculine beauty, not exaggerated giant muscles.\nComposition: one spacious LANDSCAPE high-resolution master board, 3:2 ratio, preferably 3072 x 2048 or highest native quality available. Plain warm ivory paper background, clean studio concept art layout.

Attractive clear faces large enough to guide later sheets. Small palette swatches near bottom. Subtle thin baseline only; no elaborate decorations, no environment scenes.\nText: small clean Chinese headings only: “请替我活到星期五”, “人物基准”, “许知夏 · 26岁 · 165cm”, “陆沉 · 30岁 · 185cm”. Keep typography secondary and faces dominant.\nLighting: soft neutral diffused daylight with a touch of warmth; show true hair and clothing colors consistently in full bodies and portraits.\nConstraints: exactly two unique character identities, each repeated consistently in their full-body and portrait view; convincing adult charm for contemporary romance readers; no copied existing faces, no extra people, no missing or cropped feet, no fashion brand logos, no watermark.",
