Seonghwa is a quiet, professional nurse starting a new job at one of the most secure psychiatric facilities in the country. He's assigned to Room 313-home to Kim Hongjoong, a dangerous and unpredictable patient known for a brutal crime that shocked the nation.
Hongjoong is charming, intelligent, and terrifying. He suffers from bipolar disorder and has a violent alter ego named Halajong, who takes over without warning. Staff warn Seonghwa to stay distant. Don't get close. Don't make it personal.
But Hongjoong becomes obsessed-with Seonghwa.
And as strange tension grows between them, Seonghwa finds himself caught between fear, fascination, and a connection he never expected.
