Set at an elite arts high school, Four Hands, Two Sonatas follows Kang Bi-o (Song Kang), a top-ranked piano prodigy who looks flawless on the surface but is quietly buckling under years of pressure, and Choi Jeong-yo (Lee Jun-young), a late-blooming, self-taught talent from a difficult childhood.

Byeon Hyeok-jun (Lee Jae-wook) is buried in debt when he stumbles on an ad for a "perfect" part-time job paying 50 times the normal hourly wage through a shadowy agency called Spyder Human Resource Center. The catch: the job plunges him into a hellish workplace full of bizarre, terrifying phenomena.

🏥 Doctor X: Age of the White Mafia
Kye Su-jeong (Kim Ji-won) is a genius surgeon known as the "mad dog of the operating room" — brilliant, uncompromising, and utterly unwilling to play politics. Dispatched through a doctor-placement agency to fill a surgical vacancy at the corrupt Guseo University Hospital, she proves her worth purely through skill, refusing to bow to the hospital's hierarchy or cover up its malpractice.
