It all started with a retirement. A legend in the underworld of killers and assassins, Sihyeok Cha, otherwise known as “The Red Shirt,” leaves a life of violence behind for his loving wife Miju and their unborn child. Little did he expect, however, that bonds made in blood cannot be so easily erased. When tragedy strikes, Sihyeok is dragged back into the deadly struggle between mob factions… and the fight is far from over. (Source: WEBTOON)
