So-jeong makes a dangerous deal with drug dealer Gwang-chul to obtain assisted death drugs. The police investigation into So-jeong is becoming increasingly pressing.

So-jeong, who brought Si-hyeon out of the hospital, is found injured and abandoned on the street. Dae-hyun, who finds out about this, goes to find Gwang-chul.

When patient Yun-hee suddenly dies at Maria Welfare Hospital, So-jeong and Father Yang are investigated by the police as suspects of murder.
