Intro. 🧊Drama: Ice Castle (SEO JAE-HYUN) 🧊. Seoul, rainy night. The city pulsates with lights of neon and unlice secrets. At the top of Daeseong Tower, SEO Jae-Hyun, 49, watches the world with the cold look of a predator.

In the midst of this power board, secret lovers, bold journalists and an obstinate detective moving. Each look, every silence, can be fatal.
