Art style: манга 4.
Di dalam ruang kelas sekolah yang tenang pada siang hari, remaja itu tertidur sambil berdiri di sudut ruangan, bersandar pada dinding kayu. Sinar matahari menyinari debu yang beterbangan di udara. Teman-teman sekelasnya yang kabur terlihat duduk di meja mereka. Suasana terasa melankolis dan sunyi. Palet warna cokelat muda, kuning pucat, dan putih gading.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "манга 4" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "манга 4".
Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "манга 4" idiom, not in any other medium.
