4컷 만화: 늦잠 자고 등교했더니 일요일

A vertical full-color Japanese manga comic page in polished modern anime style, 3:4 aspect ratio, featuring white margins, a thick black outer border, and exactly four horizontal panels stacked from top to bottom with clean black gutters. Main Character: A cute teenage Japanese schoolgirl with short dark navy bob hair, straight bangs, large amber-gold eyes, fair skin, blush marks, and expressive anime sweat drops. She wears a classic white sailor school uniform with a dark navy collar and red neckerchief, rendered consistently across all panels. Panel Layout: 1. Top panel: Angled high view inside her bedroom. The girl lies in bed on a white pillow and blanket, wide-eyed and mouth open in panic, with a jagged red stress mark near her head. Beside her on a wooden nightstand sits a yellow twin-bell alarm clock and a stack of books. One large rounded speech bubble on the right contains vertical Japanese text: "[もう朝!?]". 2. Second panel: Rushing outside on a sunny street. The girl sprints with a slice of toast in her mouth, flushed cheeks, sweat drops, and one fist pumped, set against dynamic speed lines, green trees, a school fence, and bright blue sky. Two large rounded speech bubbles contain vertical Japanese text: right bubble "[遅刻しちゃう!]", left bubble "[遅刻しちゃう!]". 3. Third panel: Front view outside the closed school gate. The girl stands in front of a brick gate and iron fence under green trees, looking puzzled with mouth slightly agape, holding a pink smartphone. One rounded speech bubble on the right contains vertical Japanese text: "[あれ…誰もいない?]". 4. Bottom panel: Same composition outside the school gate. The girl blushes with awkward closed-eye smile, holding her pink smartphone in realization. One rounded speech bubble on the right contains vertical Japanese text: "[今日、日曜日だった…]". Style & Constraints: Crisp line art, vibrant clean anime coloring, gentle lighting, comedic slice-of-life tone. Exactly four panels and five rounded white speech bubbles with clear vertical Japanese text. No extra characters, no watermarks, no narration boxes.
