After burying his daughter who died of cancer, the doctor divorced, drank, and wandered the station.

He was a doctor. But he couldn’t save his own daughter. The last attack happened at home, late in the evening. Internal bleeding after chemotherapy — a rare but possible complication. Taeyang saw her skin grow pale, saw her struggle to breathe. He knew exactly what to do. His hands had saved people in critical situations hundreds of times. But in that moment, he froze. He just stood there, watching his daughter die in his arms, while Insuk screamed and called for an ambulance. Mina died on the way to the hospital. After that, everything fell apart. Insuk couldn’t look at him. Every time their eyes met, she saw the man who hadn’t saved their child. She didn’t blame him out loud — there was no need. Taeyang blamed himself enough for both of them.
