Ga-Hyun (Nam Ji-Hyun) asked Shin (Kim Ji-soo) to help her remember the past. She wanted to know the man responsible for her friend's death. She also told Shin that her friend died at the same spot where she was hit by a car before the reset. Shin told Ga-Hyun to lay down on the sofa and close her eyes. Through hypnosis, Shin helped Ga-Hyun locate the criminal.
While in deep trance, Ga-Hyun traveled to the time where she was hit by the car before reset and she saw the registration number and color of the car.
When she woke up, Ga-Hyun called Hyung-joo (Lee Joon-Hyuk) and told him the hit-and-run that happened to her and Joo Hyung. She asked Hyung-joo to help her check the surveillance camera and find reports of any damaged car around that time. She saw the plate number and the color - white - of the car. Hyung-joo was hesitant to work on it at the headquarters since people may ask. Also, they are checking the past and future events.
In the headquarters, Hyung-joo went to the traffic department to check the records, and his partner saw him in the other office. They all teased him if he wanted to change to a new office.
Meanwhile, Ga-Hyun confronted Yeon-soo and told her what she thinks of Dae-sung. She told her that Dae-sung caused a hit-and-run accident. Ga-Hyun shared that she saw him use a white car when he came to pick her up. She also asked Yeon-soo if she knows where Dae-sung is. Yeon-soo denied any knowledge of him.
The following day, Yeon-soo ran away and left her house. Ga-Hyun and Hyung-joo discovered that the white car was sent to a garage. They checked the records and found the owner was Dae-sung. Hyung-joo dug more reports in the traffic department. He saw Dae-sung's car pass a few minutes along the road where Joo Hyung got hit. He tried to focus the car and saw that Yeon-soo sits on the passenger side. Ga-Hyun tried to go back again in her memory as deep as possible to see who was driving the vehicle. In her vision, she saw that Dae-sung went inside the car through the passenger seat while Yeon-soo's reflection was in the side-view mirror of the driver.
Ga-Hyun looked for Yeon-soo and asked Shin to help her. But Shin refused to help. She told her that the past is done and things have changed now. Yeon-soo messaged Ga-Hyun to see her in a secret place alone. The time Ga-Hyun saw Yeon-soo and she almost hit her. But Ga-Hyun asked Yeon-soo to surrender to the police. Yeon-soo declined and said that Dae-sung will be the one to blame since he owned the car. Yeon-soo continued that they don't need to trust Shin. She said that Shin made them believe that she contacted each one. Yeon-soo told Ga-Hyun that it was her own will to see Shin before the reset.
The next day, Hyung-joo called all the travelers and met him in the restaurant for an important matter. As soon as he saw Ga-Hyun he told her to go to the headquarters. Everyone was surprised by Ga- Hyun's situation.
