Geom Mu-Geuk

He is the second son of Wu-Jin Geom. He was an incompetent young master who could not properly compete with his older brother and was easily deprived of the position of successor. However, when he lost everything, from his father to everyone around him, he decided to use The Great Regression Technique. After many years, he gathered all the necessary materials for the regression technique and decided to return to the past to take revenge on Moogi Hwa.

After being able to reach the past, his goal would be to kill the one who deserves to die and save those who should not die. Because he lost everything to Hwa Moogi, he has a vengeful side, but more than anything, after losing everything to Hwa Moogi, he looks back and says he has no good memories, and tries to get closer to his father by talking to him, for his own good.
