Baek-On and Ho-Yeon are exorcists for hire, traveling throughout the country in search of grudges and ghosts. Each encounter reveals a story of tragedy and loss, sentiments they are all too familiar with themselves. At last, we learn the truth of Baek-On's past, how he has shouldered the punishment and revenge of the spirits that was meant for his father. Even worse, Baek-On knows that these painful events will repeat themselves into his next life and the next, time and again until his soul is spent. The cycle of hatred and love continues in the final volume.
