Baek-ryeon expects Sang-hyuk, who heroically saved her from her stalker, to be the man of her destiny, but he draws the line that he does not want to be in a relationship with a human. Meanwhile, Sang-hyuk and Jae-hee run into each other at Baek-ryeon's animal hospital. How were they related to each other in their past lives?

500 years ago, Cheon Sang-hyuk, a fairy who had no ties to humans, ignored the warnings of Samsin and fell in love with a human girl. As a punishment, his wings got burnt off and he lost his beloved woman. 500 years later, since he well understands the pain of being alone, he empathizes with Baek-ryeon and eagers to help her out. So he starts by asking her what her ideal type is.

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.
