Synopsis
While You Were Sleeping is a combination of the romance, legal drama and fantasy genres, focusing on the tale of three young adults who have acquired the ability to see the future through their dreams: field reporter Nam Hong-joo (Bae Suzy), rookie prosecutor Jung Jae-chan (Lee Jong-suk), and police officer Han Woo-tak (Jung Hae-in). Some of these dreams show crimes that Jae-chan has to investigate and others show disastrous events that one or more of them will have to endure. Conflicted by these dreams, the trio collaborate with each other to prevent their ominous dreams from turning into reality and to defeat their archenemy, the corrupt lawyer Lee Yoo-beom (Lee Sang-yeob).
Cast
Main
Lee Jong-suk as Jung Jae-chan 정재찬
Nam Da-reum as young Jung Jae-chan
A 29-year-old rookie prosecutor. Jae-chan was the son of Jung Il-seung, a police chief officer who was murdered by the same runaway soldier who killed Hong-joo's father. Back in his adolescent years, he was a carefree boy with no worries about his studies. After reconciling with his father, he became a changed teenager and aimed to work as a prosecutor. It was also at this age that he acquired from Hong-joo the ability to see the future through dreams, when Hong-joo saved him from drowning in a lake while preventing police officer Choi Dam-dong, the runaway soldier's older brother, from committing suicide.
Despite appearing cold and lacking a sense of humor, Jae-chan is still foolish and funny in some aspects. Since the first appearance of his future-seeing dreams, he will do everything he can to prevent them from coming true. He falls in love with Hong-joo after days of going out with each other, without knowing or recognising that she was "Bamtori", his childhood acquaintance who also lost her father to the runaway soldier (his lack of recognition was due to him remembering Hong-joo as a boy from her tomboyish mannerisms and short, boy-like haircut). He was born in April 1988, and his blood type is B. Despite all the chaos he somehow managed to fall for Nam Hong-joo and is very protective towards her.

Shin Yi-joon as young Nam Hong-joo
Born in 1988, Hong-joo is a 29-year-old journalist and field reporter who has the power of precognition (the ability to see events in the future), which takes effect while dreaming. She was once a tomboyish girl nicknamed "Bamtori" (밤톨이; lit. 'Chestnut') who aspires to become a baseball player. Since she was a child, Hong-joo has been haunted by seeing the deaths of other people in her dreams, one of which is the untimely death of her father, Nam Chul-doo, at the hands of a runaway soldier who also killed Jae-chan's father. She first met Jae-chan when both their fathers' funerals were jointly conducted on the same date in the same funeral hall. By saving Jae-chan from drowning, she had inadvertently made Jae-chan acquire the same ability that she has. Due to her short haircut and tomboyish characteristics, many people, including the reporters of the runaway soldier case and Jae-chan mistook her as a boy.
