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. Baekryeon 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 Baekryeon's unofficial hypnosis records.
