Cheon Sang-hyuk, trapped on Earth as matchmaker for 500 years, helps Oh Baek-Ryeon, cursed for past sins to fail every love affair. Just as she loses hope, Sang-hyuk appears, revealing himself as her fairy Cupid.

Baek Ryeon feels a weird sense of familiarity upon encountering Cheon Sang Hyuk. He secretly watches her wondering why she doesn't have the red thread of fate unlike the other humans. Meanwhile, the night before the snowstorm, a woman gets kidnapped in a public parking lot in Mt. Inwang, and the witnesses of the incident are found dead one by one.

Baek-ryeon hopes Sang-hyuk, her rescuer, is destined for her. He refuses a relationship. Sang-hyuk and Jae-hee meet at Baek-ryeon's clinic. They share a past life connection.

In the distant past an elf falls for a human despite warnings. His wings are burned as punishment and he loses her. Centuries later he helps another out of empathy for her loneliness, having known such pain himself.

Sang-hyuk suspects the Inwangsan missing girl case and 1993 missing high school girl case share a culprit. Upset, Baek-ryeon crushes on Sanghyuk though he sets her up randomly. Climbing Mt. Inwang, she meets destiny's man.

Sang-hyuk and Jae-hee discover Baek-ryeon witnessed the Inwangsan disappearance. Sang-hyuk pursues the criminal to safeguard her. Baek-ryeon questions Sang-hyuk's identity after he shields her unharmed.

Sang-hyuk stays at Baek-ryeon's house and dreams of Jeong-ah, who warns Baek-ryeon not to let go of the hand of the man of destiny. A criminal stalks Baek-ryeon as murder victims increase.

The disappearance of a high school girl in 1993 still remains unsolved as Sang Hyuk, who was in charge of the case, has disappeared from the human world for decades. Sang Hyuk is convinced that the culprit of the missing high school girl case and the culprit of the Inwang Mountain missing woman case are the same person, and he actively participates in the investigation.

Baek Ryeon goes to find the street she saw in her dream. Although it is her first time to see that street, she feels strangely familiar and her heart starts to ache. The more Sang Hyuk learns about his feelings for Baek Ryeon, the more he becomes afraid of approaching her. He doesn't believe he deserves her.

Sang Hyuk remembers Baek Ryeon saying she was an angel when she was drunk, and he secretly hopes that she actually is an angel. Meanwhile, Go Eun Seo, a missing woman from Mt. Inwang, calls Baek Ryeon and tells her that she is alive and asks her to come. Baek Ryeon goes alone to the address where Eun Seo is.

Baek Ryeon sees her past life during her surgery, and is confused because the angel in her past life resembles Sang Hyuk. Meanwhile, Jae Hee begins to have doubts about Sang Hyuk's identity, and the legal hypnotist Cheong Il gives Sang Hyuk Baek Ryeon's unofficial hypnosis records.

Jae Hee informs Baek Ryeon that Sang Hyuk is not human, and Baek Ryeon suddenly remembers Sang Hyuk's missing hand. Meanwhile, she realizes that she forgot to climb the mountain one last time so she goes to Inwang mountain to complete her mission. Jae Hee and Sang Hyuk also head there to find her.

The police arrest Kim Myeong Sik as the prime suspect who finally confesses that he killed Go Eun Seo. He claims that there will be no more victims since he will be locked up. Meanwhile, Jeong Ah's parents come to Baek Ryun's animal hospital, and Baek Ryun suddenly sheds tears as she hears the story of their daughter's disappearance.

Just before his final "metamorphosis", Sang Hyuk finds out who Baek Ryun is and feels very confused. After hearing that once he enters the transformation phase, nobody can tell when he will come out, Baek Ryun fears that Sang Hyuk will disappear forever. Jae Hee happens to see a portrait of Sang Hyuk and So Hee, and he visits Sang Hyuk to ask who the woman in the painting is.

When Kim Myeong Sik, whom everyone identified as the culprit, gets murdered, the case becomes even more mysterious. Baek Ryeon hears the criminal's voice in her dream, which reminds her of some voice she heard in real life recently. Meanwhile, Sang Hyuk conducts a large-scale search of the Jongseo Gu area with several clues.

Baek-ryeon faces the same fate as 500 years ago when Sang-hyuk spared her life but was punished. Now bound in metamorphosis, Baek-ryun confronts crisis due to Song's scheme.
