"The fate they can't get away from."

As soon as Jun-o gets up, he goes to Young-hwa and tries to kill her. However, he fails to do so because of a mysterious shield that protects her. To get past the protection and seek the chance to kill her, he decides to get close to her. Young-hwa finds Jun-o odd, but she tries to understand him, thinking he’s suffering the trauma from the accident.
