She loves and cares deeply about her older brothe Euntae. However, for 5 years, she held a grudge against Euntae due to Euntae turning into a vampire and seemingly abandoning their parents, and only learned of the truth years later. While at first she was scared of vampires, she has seemed to overcome those fears. Despite holding a grudge against Euntae, at some level she still cared for him and didn't turn him in to the Vampire Hunting Corps.

Background
As children, Euntae and Haeun lived in poverty, with their parents having abandoned them and disappeared years ago. They were taken in by their Aunt, who could only let them stay in a small rooftop closet. The aunt, however was physically abusive. Their parents suddenly came back into their lives and were able to find financial success. While Euntae learned that their parents became vampires, Haeun was unaware and felt they could finally be a family. On their way home from a family vacation, the family's car breaks down and they get stranded. Unbeknownst to Haeun, they were staying at a vampire compound. She was eventually attacked and knocked unconcious by vampires, but saved by Euntae. Euntae, having turned into a vampire to save her, did not tell Haeun the truth about what happened or why he was a vampire. This led to Haeun holding a grudge against her brother and moving out.

Plot
Haeun is a student at a university, and works as a part time advertising model to help pay her dues. She is in a relationship with a young man. One day, her apartment catches on fire. As she laments the loss of her apartment, Hayan Park shows up to help, rescuing much of Haeun's belongings. The two very quickly become friends and bond when Euntae arrives to check on on Haeun. Haeun reveals her relationship to Euntae and coldly dismisses him.

Later that evening, Haeun and Hayan meet at a park. Hayan, having learned of what happened between the siblings, tells Haeun the truth and that Euntae has been Haeun's benefactor, acting as their uncle as he was still too ashamed to face her. Hayan also reveals that she is a vampire. This shocks Haeun, but does not appear to affect their friendship. The two also make plans to arrest the arsonist that set Haeun's apartment on fire, whom they suspect is Haeun's boyfriend. As part of the plan, Haeun temporarily moves into her boyfriend's apartment while hers is being repaired. Her boyfriend takes her hostage, giving Euntae and Hayan the proof they need to arrest him. As Euntae prepares to leave, Haeun confronts Euntae over how he pretended to be their uncle to help Haeun. Euntae attempts to leave, but Haeun sees that Euntae still carries a key charm she made for him years ago. This causes Haeun to emotionally break down and beg Euntae to be back in her life. The two reconcile at dinner later that night.

Haeun moves in to Euntae's apartment. She continues to go to school and helps Hayan any time she can.
