Lee Soohyuk was on the brink of death dying from thirst after being newly turned and with no one to help him during his transformation a strange man, a vampire, found him and decided to become his mentor. This man had trained him in his abilities and skills but uncovering the truth would have lead to his mentors death as it was his mentor who transformed him and came back out of guilt. The worst part was that his mentor was panning to kill and get rid of him for becoming too powerful. Soohyuk would have been able to find out more about his human life if his mentor hadn't interfered and destroyed any evidence of his existence. It was suspected that he was in a high position, a leader, a husband and also military defending and serving his people. Out of rage discovering the truth, he killed his mentor. at some point he got bored and tired of killing and hurting others out of anger unless he needs to for survival.
