A dramatic webtoon illustration in the exact art style of the manhwa "High School Conquest" (고교정벌), sharp cell shading, clean line art. Modify the reference image by moving all characters to the left side: exactly three high school students are sitting only on the desks on the left half of the classroom. The entire right half of the classroom, including all desks and chairs on the right, must be completely empty and clear. The three students on the left are turning around in complete shock and terror, looking backward at the viewer with wide, frightened eyes. The green chalkboard remains clean and blank. Keep the exact frontal perspective and style.
