"The Innocent Man" Park Si Yeon committed murder 7 years ago and the reason behind it was revealed.

On the October 4th episode of the KBS drama "The Innocent Man," they revealed the truth about what really happened in the murder that Park Si Yeon allegedly committed.

7 years ago, Han Jae Hee (Park Si Yeon) headed to a model after receiving a report from a witness. The man, who claimed to have worked at Tae San Group, said that he had evidence to prove the CEO's corruption. 

However, Han Jae Hee says, "You think this will finish him? It won't end Tae San Group. Think about it for a day and call me back," and tries to leave. The civilian, who was already drunk, had already been embarrassed by her attitude. He says, "You know him don't you? People said that there's a reporter he likes and so it must be you. How can a reporter be this sexy?" and tries to sexually assault her. 

Jae Hee, who was fighting back and trying to get him off of her, strikes him with a glass bottle and the man, who falls backward, hits his head on the corner of a set of drawers and dies. Jae Hee, who didn't mean to kill him, calls Kang Ma Ru and he decides that he will take all the blame for it for Jae Hee, whom he loves. 

In the episode, Jae Hee tries to come back with the proof that the witness gave her 7 years ago when the CEO finds out about the relationship between Jae Hee, Ma Ru, Ahn Min Young.
