Limited Series

Eun Chae-ni is the granddaughter of a wealthy restaurant owner. Sharp, courteous, and diligent in every undertaking, she carries a heart that sets her apart, growing more stubborn as she matures, and she treads life on a knife-edge that could snap at any moment, all while yearning for a train trip. Lee Woon-jung is a cryptic civil servant, cloaked in secrets and short on social grace. A loner who can hardly stand beside anyone, he gradually discovers the meaning of 'us' upon meeting Eun Chae-ni.
