Art style: манга 4.
Tampilan dekat tangan protagonis yang gemetar memegang selembar kertas surat yang kusut dan kotor. Tulisan tangan yang kasar terlihat di bawah cahaya lampu kuning yang redup di dalam sel. Di latar belakang, jeruji besi yang berkarat terlihat buram. Suasana penuh kesedihan dan keputusasaan dengan warna kuning pucat dan cokelat tanah.

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.
