Mr. Shin may look like an ordinary chicken shop owner, but he’s the kind of person who appears just in time—when tempers flare, fists are about to fly, and chaos looms—to cool things down with one sharp, satisfying line that settles everything. When Philip, a by-the-book rookie judge, is suddenly reassigned to the chicken shop instead of a courtroom, and Sion, a delivery rider secretly working as Mr. Shin’s informant, joins the team, the unlikely trio begins to chase the truth and seek new ground for justice. Everything seems to be running smoothly—but one question remains: Who exactly is Mr. Shin?
