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.
Now that she is fatherless, Hong-joo began dreaming of the impending deaths of her mother, Yoon Moon-sun, and herself: the former happening due to an accident she gets into and the latter due to her occupation as a field reporter. Unfortunately, like all the other dreams, she does not know when the deaths will happen; she can only guess. In her attempt to stop her dreams from becoming reality, she leaves her job and helps her mother in running a samgyeopsal restaurant. Nevertheless, she regains her resolve in doing her job as a field reporter with Jae-chan to support her in preventing their dreams from coming true. She later in the series falls in love with Jae-chan and begins dating him.
