"Secret Love" Ji Sung is determined to take revenge on Hwang Jung Eum.

September 26, the 2nd episode of the new KBS drama "Secret Love" featured Ahn Do Hoon (Bae Soo Bin) taking on the case as prosecutor for the hit-and-run case of the woman Seo Ji Hee (Yang Jin Sung) that he is secretly responsible for.

On the night of Kang Yoo Jung and Ahn Do Hoon's 7th year anniversary, the car slips in the rain and Ahn Do Hoon ends up hitting Seo Ji Hee with his car. Even though Ahn Do Hoon finds Seo Ji Hee on the ground, he leaves the site of the accident to hide the fact that he had been drinking.

Seo Ji Hee dies soon after and the owner of the vehicle, Kang Yoo Jung is named as a suspect. When the police question her about the person who had been driving the car at the time of the accident, Kang Yoo Jung lies and says that she was the driver.

Coincidentally, the prosecutor in charge of Seo Ji Hee's accident is Ahn Do Hoon. Without knowing the fact that Ahn Do Hoon is purposely trying to hide the truth about the accident, Kang Yoo Jung is determined in proving her innocence one she arrives in court.

Even though Kang Yoo Jung says that she didn't know about the hit-and-run accident, nobody believes her since blood was found on the outside of the car.

Jo Min Hyuk (Ji Sung) arrives at the police station after learning about the accident and says to Kang Yoo Jung, "Are you the one who killed her?" Kang Yoo Jung apologizes but Jo Min Hyuk violently pushes her and begins to strangle her. Jo Min Hyuk says, "Someone like you dares to mess with something that belongs to me?" then punches the wall next to Kang Yoo Jung's face.

Jo Min Hyuk continues, "This is not something that is going to end by saying sorry. You don't know how much I've been hurting." Police officers drag him away. Jo Min Hyuk becomes determined to take revenge and says, "I'll see you again designated driver."
