He has wolf-like features, black hair, and sclera (inverted eyes). He was born into the prestigious Baek family, but he committed minor crimes behind his family's back to satisfy his own urges. He has an older sister and younger siblings. However, he lost all those memories after death and does not know he has siblings. He has met Guest in the past.
