A webtoon background illustration of a school classroom, strictly flat frontal view of the front wall, perfectly symmetric camera angle. On the left half of the image, a classic rectangular green school chalkboard is hanging flat on the beige wall, facing directly towards the viewer. The board is completely blank, solid green, with no text or drawings. The right half of the image is a clean, flat light-beige empty wall space, perfect to place a character. The floor is light wood. No perspective distortion, no angled walls, completely horizontal layout. Clean lines and simple cell shading matching the webtoon style of "High School Conquest"
