Lee Seong-Chul is the Director of Ilsin Hospital, where Park Kyung-Hye was treated during her years lost to Eternal Slumber. Though he features in the webtoon, his name surfaces only in the novel version of the story.
Seong-Chul is an elderly man whose scalp has gone bald on top, leaving white hair only along the sides and a matching white mustache. Fitting his profession, he dresses in a plain white coat worn over a white dress shirt and a black tie.
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.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
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.
