Now that Woo Hyeol is awake, Sang Hae and Dong Seop believe it’s a good idea for them to move into the guest house. If he does collapse again, they’ll be around to help (and they also don’t have the money to afford their rent increase). The two vampires are elated when In Hae agrees to the idea. Woo Hyeol confesses to his friends that she likes him and that he likes her. 

Out on delivery, Rose smells fresh blood coming from a strange house. When she returns in the daylight she finds Man Hwi leaving the house. This worries her. 

Hae Won visits Do Shik. He confirms her suspicions that Woo Hyeol is a vampire. Later, Man Hwi comes to the office. He reveals to Do Shik that there is something off about him, almost like his vampire powers have diminished. Neither one of them realizes that he is the half-vampire. If Man Hwi wants to get paid, he’s going to have to show Do Shik the scare that proves he is the one he wants. 

Unable to find a sitter, Gwang Ok convinces In Hae to watch his son, Min Jae (Kim Do Geon). Apprehensive at first, Sang Hae and Dong Seop convince her and Woo Hyeol to take the boy to an amusement park. They can look at it like a date. 

Once in the park In Hae has the time of her life, especially after Woo Hyeol, the big bad vampire is easily scared by fake ghosts and carnival rides. Woo Hyeol is just excited to see her smile. Completely worn out Min Jae falls asleep hanging from Woo Hyeol’s back.

While In Hae brushes off the moment, Woo Hyeol presses Sang Hae about what he’s doing pretending to be a detective. He confesses that it’s to find his missing gold. he also confesses that he believes In Hae’s father may have been kidnapped. Woo Hyeol advises them to keep the information to themselves for now. He doesn’t want to worry her if possible. 

Later, Woo Hyeol finds In Hae eating alone. Taking a few bites of food, he gets tipsy, but not drunk. As the two talk under the moonlight, she tells him that she wants to give him her blood. She is happy to help him. She wants to help him. They agree that it will be on the 100th day anniversary of the day that they met. She’ll throw him a party. It will be a grand celebration. 

While Do Shin contemplates what would drive an immortal vampire to want to become human, Man Hai returns to his secret house, with an unconscious man thrown over his shoulder. He takes him to the basement, where there are several other men in cages. They are his source of blood. One of them is In Hae’s father. 

While In Hae and Woo Hyeol assign cleaning duties, So Yi, the long-term guest in room 201 introduces herself. Though she’s confused about how the house has more staff than guests, she walks away when her phone rings. The caller is someone she doesn’t want to talk to, and she promises that if they call again, she’ll call the police. 

While Woo Hyeol and In Hae flirt while doing the laundry Hae Won arrives at the guest house. In a moment of kindness, she compliments how great the two look together. Taking In Hae to a nearby cafe, Hae Won asks why she never told her that Woo Hyeol is a vampire. All niceties aside, Hae Won then tells In Hae to get out of his life. That she is the Hae Sun he’s been waiting for. When In Hae refuses, stating that she will follow her heart, Hae Won promises to do the same. She then goes to Do Shin and tells him to do something. She’s tired of watching them fall in love right under their noses.

While Sang Hae and Dong Seop pack up what little belongings they have in their old apartment Rose drops by. She tells them of the creepy house and that she saw Man Hwi coming out of it. 

On the roof, Mr. Ko confesses that the only way for Woo Hyeol to become human is to sacrifice In Hae. If he doesn’t, then the only way she can continue to live, is if she kills him. Between the two of them, only one of them is going to be able to survive. 

Standing on the ground outside the mansion, Man Hwi overhears the conversation. He confesses everything to Do Shik. Who rushes to the guest house and picks a fight with Woo Hyeol. As the two fight, a man walks into the house and immediately makes his way to room 201, and tries to force So Yi to leave with him. 

Rushing to help her, In Hae puts herself in danger. Though the man introduces himself as So Yi’s boyfriend, she says he’s nothing more than a stalker. In Hae will not allow him to take her and continues to fight. Sensing she’s in danger, the bite scar In Hae left on Woo Hyeol pulses, revealing itself to Do Shik – who knows now he is the half-vampire he needs to kill for himself to live. 

Knowing she’s in danger, he rushes inside. he fights off the attacker, but realizes that In Haehas been injured and she’s bleeding. Hypnotized by the blood, Woo Hyeol almost bites her. Luckily, Do Shik rushes in just in time. 

Quick Take: The more we see Hae Won the more I hate her. She’s a delicious villain. The look on Do Shik’s face, when he realizes that Woo Hyeol is the vampire he’ll have to kill, makes him wonder if he is not as bad as we think. However, Man Hwi is awful. 

What will Do Shik do now?
