Here’s a not so quick recap of the story so far! While looking into Han Gyo Min (Jae Hee) disappearance, San (Lee Joon),Gyeo Wool (Lee Se-young) and Goo Hyung (Oh Jung-se) stumble across a vampire bar. After a shootout San got inject with a blood serum that heals him no matter what, and turns him into something similar to a vampire. Later the trio were hired to protect the newscaster Seo Seung-Hee (Choi Song-hyun), and while figuring out that case San uncovers more information out about the vampire bar and how they obtain their food supply. The more that San looks into the case there are more links there are to Jung Yoo Jin (Kim Yoon-hye) being part of an illegal organization. San later gets a call from an old cop acquaintance, Choi Seon Yeong, and he help her get into her father’s safe where they find pictures of Yoo Jin and Kang Tae-Woo (Jo Bok Rae) that her father, Jang Tae Shik (Choi Gwi Hwa), would have used to make fake ID’s. The trio is hired to clear Moon Gyeong Ho of murder charges, which they do, however their client isn’t who they say they were but in fact a woman by the name of Yo Na (Lee Chung Ah) who seems to have a connection to Yoo Jin. Yo Na calls San after a case and asks for a meeting to which he agrees to. Now on to this episode!
Ji Woong gets left at a peer by a driver and gets handed a new identity. He tells the driver to tell Yo Na not worry since he is an expert and changing identities. After the driver leaves Tae Woo and a group of men come to see Ji Woong. He reminds him that he should be scared of him and Ji Woong warns him about Yo Na. They get into a fight where Ji Woong pulls a knife, and you would think that it would give him the advantage over an unarmed man. However when he does stab him multiple times in the gut it doesn’t seem to bother him. Tae Woo took the knife and stabs Ji Woong multiple times telling him again that it’s him who he needs to be scared of, and them seem to leave him as dead.
San arrives at the club to find Gyeo Wool, Goo Hyung, Doctor Hwang and Se Ra already there. San is really confused however Goo Hyung things that San arranged this so that it would cheer him up. San gets called up to see Yo Na and when he steps forward her bodyguard stops him. There is then a fight between him and the bodyguard until Yo Na tells them to stop. She invited him here to prove to him that she is the owner and he is the hunting dog.
They walk through the club into the back alley and San notices the vampiric activity and asks her if she made them that way. She doesn’t answer but instead makes a formal request to have San find someone for her. He asks why he should agree and she tells him that if he doesn’t his friends will be killed. She also tells him that if he tries to save them, they will also be killed. She tells him that the club is open until 6am and he has until that time to find the person she’s looking for. San is given the keys to the car and he and Yo Na get into the car.
San drives them to an empty warehouse, and Yo Na tells him that he should sniff around. He tells her that he is only going along with this because of his friends. When San gets out of the car Yo Na pulls out an old photo of Joo Young Kwang. She reminisces about the day she was eating breakfast with her mum and Dal Soo and he arrives. She fell in love at first sight with him, and we find out that Yo Na’s original name is Eun Hye.
San goes through the warehouse and sees a spill on the ground that contain blood and he sees the person break the bottle. He goes through the file room and find paperwork for the King Salon. He also looks through the trash where he finds a receipt for an order of UV lights. He hears something and goes after it. He sees someone but couldn’t catch up with him. He meets up with Yo Na and asks who that was. She stipulates that it looks like there are rats about, and he asks if there are more which she doesn’t know. He shows her what he found about the Salon, and before they leave San asks if the man that they are looking for is even human.
Yo Na and San arrive at the salon and he asks for a trim. The barber asks if it’s his first time, which he admits it is. While he is shaving him, he asks the barber if he knows Young Kwang, because he was there the day before. The barber tells him to stop talking so he doesn’t cut him. San asks again and 2 guys who are at the counter stand and the barber mentions that he wants to finish this quickly because there are other customers. Yo Na mentions that they are too neat for being customers. San twists the barber’s arm and wipes off shaving cream and beats up the 2 other guys with the towel. Yo Na steps on the throat of the barber and tells him that if he doesn’t talk she will kill him. San notices him looking at the phone and sees that there are multiple calls to and from Blue Moon bar.
Back at the bar, Goo Hyung is dancing with a woman and Se Ra is jealous she is determined to with Goo Hyung over. When Se Ra heads to the dance floor Gyeo Wool wonders if Goo Hyung won the lottery. Doctor Hwang tells her that it’s a war amongst women and she should go up. She tells him that in war it is best to be neutral.
While they are driving Yo Na notices that they have picked up a tail so they lure them to a secluded area. San has another fight scene and Yo Na thinks back to the time that she was running late and Young Kwang gave her a lift on his bike. She tells him that he will be a cool doctor and he tells her that he’s much prefer to be a good doctor over a cool one. She teases him if he is her doctor, and he tells her that if she’s sick he will nurse her back to health forever. There seems to be mutual attraction between them. When Yo Na was dropped off her friend Soo Yeon asked about him and she tells her that he’s the new exchange student living in their house.
When the tail receives a phone call Yo Na answers it. She tells the person on the other end that if they are following her it means that they haven’t found him yet. She also tells him to not worry about his runner because she’ll take care of him.
Back in the car Yo Na tells San that he is not the only one with a time frame, she’s worried that if she doesn’t find Young Kwang tonight that she’s scared he’ll die. They arrive at a store to find it open at 3 am which they find odd. They find the owner and San asks about Young Kwang. Yo Na notices that the wine that she’s drinking contains blood and asks her why. The owner simply hands them a business card to a bar.
Yo Na goes to freshen up her makeup and thinks back to a shopping trip she had with Soo Yeon. (Yeah there is a lot of flashbacks but we’re learning about Yo Na). They are shopping and there is a floral dress that catches Yo Na’s eye. She doesn’t have enough money for it, and isn’t sure that’ll it’ll be there in a few days. She sees Young Kwang and calls to him, and he responds. They walk home and he asks about Soo Yeon, which Yo Na takes as him being interested him her so she tells him if he’s interest he should give it a try and walks away. The next morning she’s still mad and Young Kwang tries to make it right. Soo Yeon shows up wearing the dress that she wanted to buy, because Dol Soo is bugging her to go to the river she yells at him and leaves. Young Kwang finds her out back and asks her why she’s so angry. She admits she doesn’t know, but Soo Yeon showed up wearing the dress she wanted and she didn’t like the he was staring. Young Kwang suddenly understands so he scotches over and kisses Yo Na
Gyeo Wool is worried about San since they haven’t seen him since earlier, however Se Ra and Goo Hung only want to dance. She tries calling him again, still no answer. Gyeo Wool goes to the bathroom to wash her hands and she sees someone washing blood off her hands. Gyeo Wool gets a really bad feeling and tells them that they should leave. This falls on deaf ears however because Se Ra and Goo Hyung still want to dance and they drag Doctor Hwang on the dance floor as well. When Gyeo Wool goes to leave, she’s threatened by the staff that it would be best if she stays until San returns.
Yo Na and San goes to the bar and Yo Na asks the bartender if he knows Young Kwang. He tells her that he’s not there and San mentions that she asked if he knew him, not if he was there. He offers a deal that he will tell them the information they need if they look for someone for him. Yo Na tells him when they have more time and San promises that they will look for Min Tae Yeon after they find Young Kwang.
One last memory! Yo Na and her family were waiting for Young Kwang to celebrate her birthday. They think that they hear him. However when Young Kwang does arrive he finds everyone dead, and Yo Na is just barely holding on. However instead of healing, she turns into a vampire. He takes her to the hospital and finds her feeding on another patient, and he realises that he needs to find a solution.
Young Kwang starts killing people and harvesting blood for her. At first it really bothers him but then it just becomes routine. One day he arrives home to find Yo Na missing, and when he goes searching for her, he finds her feeding on a man. He tells her off for leaving the apartment and she tells him that it’s been 10 years, how much longer does she have to hide. He kills the man and tells her he refuses to let blood stain her hands. He starts working for an organization that distributes blood. One day Young Kwang refuses Yo Na’s advances because he’s become a monster because of her, and she mentions that no one ever asked for him to become a monster. He tells her that it was a sacrifice that he made for her. Yo Na reminds him that a human’s sacrifice ends in death and he admits that nothing lasts forever.
Yo Na meets up with a much older Young Kwang, and hugs him. She tells him that they have to leave. Soo Yeon comes out and is in shock for seeing her friend for the first time in years and she hasn’t aged. Yo Na puts two and two together and asks Young Kwang to choose between her and Soo Yeon. Young Kwang confesses that he has always wanted to be her sun, however he is too old and too tired to be any good to her. Yo Na tells San to kill Soo Yeon but he tells her to think about it.
Yo Na reacts and bits Soo Yeon’s neck and tells Young Kwang that it’s over and he should come with her. He tells her that he shouldn’t have helped her stay alive, and she should have died. He tells her that he needs to stop the evil he helped create. He turns on UV lamps which burn Yo Na however San takes off his jacket and covers her until the lights turn off.
San sees Tae Woo and runs after him. By the time he gets to the alley he is already driving away in the car and he has hurt again. He screams in agony before running back to Yo Na.
Back at the club, there is a countdown until 6am. What will happen to his friend? We’ll find out next week.
