Sang-hyuk begins to suspect that the culprit in the Inwangsan missing girl case and the 1993 missing high school girl case are the same person. Baek-ryeon is upset because Sanghyuk tries to set her up with a random man while she has a crush on none other than Sanghyuk himself. At last, after climbing Mt. Inwang a thousand times, she gets to meet the man of destiny.

Sang-hyuk and Jae-hee learn that Baek-ryeon was a witness to the Inwangsan disappearance incident. In order to protect Baek-ryeon, Sang-hyuk chases down the criminal like her knight in shining armor. Baek-ryeon is happy when Sang-hyuk protects her like Superman and doesn't get hurt even after the intense physical fight, and she gets very curious about his true identity.

Sang-hyuk, who stays the night at Baek-ryeon's house, dreams of Jeong-ah, and in the dream, Baek-ryeon is warned not to let go of the hand of the man of destiny. In real life, Baekryeon is put in danger as the criminal constantly keeps his eye on her while the number of murder victims increases.
