William Will Woo is a member of the Original Seven and inherits from a noble family. On the outside, he appears composed, but inside, he's filled with anger and turmoil. His father was seen as an adversary and competitor for his mother's exclusive love. As a teenager, Woo attacked his dad with a knife in an attempt to murder him. However, his mom intervened and took the blow instead, resulting in her death. Following this incident, Woo left the township where his family had ruled due to the painful memories. Since then, he has become increasingly unstable mentally and seeks to release his pent-up rage in any way possible.
