Personality

At heart Seong-Chul is driven by scientific curiosity, eager to keep Kyung-Hye under observation so he could understand the source of her recovery. That resolve evaporates in the face of influence, however: the moment he realized her son Sung Jinwoo held S-Rank status, he abandoned his stance entirely.

History

When Kyung-Hye stirred awake after four years trapped in Eternal Slumber, Seong-Chul at first declined to discharge her, wanting to study how the impossible cure had happened. Learning that her son was an S-Rank hunter changed his mind instantly, and he released her without further argument. It is also suggested that he stayed silent about the miraculous case, since Yoo Myunghan and his team had to investigate on their own to uncover that she had been healed.
