Excruciating pain

Woo-joo is a host who treats trouble—including arrest and prison—as an ordinary part of life. Then names begin appearing engraved on people’s bodies, and he recognizes the name as his own. In a prison cell, Woo-joo meets Ji-hoon, whose name is engraved on the back of his neck. Ji-hoon asks whether Woo-joo remembers him, calling him “hyung.” With nowhere to run or hide, Woo-joo faces a man whose way of confronting him is very different from the childhood he remembers.
