Flames of Digital Vengeance

In the fictional nation of Silla, a young woman named Hana jumps to her death after a viral online shaming campaign falsely accuses her of arson. Years later, her brother Jin, a reclusive tech genius, uses advanced surveillance and hacking to systematically hunt down every commenter who called for her death, delivering poetic justice through fire and fear. A detective caught between the law and his conscience must decide if breaking the rules is the only way to stop a killer who has already redefined the boundaries of justice.
