Ms. Jung wants to know how Sung Min will die, and she tells Tae Pyung that she doesn't want to see him die before her death. Sung Min wants to know who is going to kill him. Tae Pyung tries to stop Sung Min's death, but it's not easy. Meanwhile, Tae Pyung encounters Joon Young at the hospital, but he can't see her death in her eyes.
