But that was not the case for Jin Yi Soo.

Showing how dedicated he was to his new work, he didn't let his personal problems get in the way. He helped the team gather evidence that would lead them to the possible culprit.

Their first suspect was manager Woo Sang, who was found covered in blood on the day that Yura died. The suspect was Jin Yi Soo's former classmate, though he confessed that he didn't do it.

Jin Yi Soo also mentioned to Detective Lee that he was not the suspect because he was too smart to commit such a crime that would ruin his reputation.

However, in the last scene, the team found CCTV significant to the case. The video showed senior actress Baek Sang Hee slapping Yura in front of their colleagues.

In addition, her DNA also matched the evidence found in Yura's body.
