Mission Impossible? Not If Hae Seong Can Help It!
Seo Kang Jun is absolutely killing it as Jeong Hae Seong, a top NIS agent who’s gone undercover at Byungmun High School to track down Emperor Gojong’s missing gold. Sounds intense, right?

If she succeeds, it’s game over. No more undercover work, no more secret mission, and worst of all, no more access to the hidden gold. Talk about pressure!
