Gyeongseong Detective Office

The dazzling sleepless city of Gyeongseong, a city of extravagant desire.

The doors of the Gyeongseong Detective Agency at 45 Myeongchi-jeong Ilgok opened.

An orphan with no one in the world,

16-year-old Sohwa, who has only her spirited nature to rely on, falls into a secret trap.

"No! I really don’t know anything! Really!"

Jeong Haegyeong, a young man who runs the detective agency alone.

The girl he encounters by chance brings back memories of a past he wants to forget, and Haegyeong ends up moving to save Sohwa, who has been falsely accused.

"If I only tell you my name, will you search all of Gyeongseong for me?"
