Na Jiseong

Jiseong holds the position of Vice Minister of Treasury while also serving as the Deputy Chief Scholar at Gyujanggak Library. Known for his quick and accurate calculations, he was recognized for his abilities early on and rapidly promoted within the Ministry of Treasury. The Minister of Treasury selected Jiseong as his successor and gave wings to his career by recommending him for the concurrent position of Deputy Chief Scholar of Gyujanggak Library.

Perhaps due to his early success, he treats and looks down on his subordinates with an arrogant attitude, resulting in a poor reputation among those around him.
