Title: Bloody Sweet
Shin Naerim's life isn't going so great. She's being bullied at school because her mother is a moodang (Korean shaman), and her only solace is online, where she writes web novels and keeps up with a blog. Though she is bright and cheery online, she cannot even speak in real life because it would only entice the bullies further. So instead, she spends her days silently taking every comment and nickname (“wig,” being the main one, short for “witch girl”), waiting for her high school life to finally be over so she can move on with her life.
Unfortunately, there is still more high school life to contend with, and next on the docket for Naerim is an overnight school field trip. As if it isn't enough for her to deal with the name-calling and abuse during the school day, now she has to do it overnight. Even more unfortunate is that there is an abandoned church nearby where they are staying. It is the perfect backdrop for more bullying of the “witch girl.”
However, these school girls don't know that just because a place is abandoned doesn't mean it is empty. While forcing Naerim through the abandoned church, they encounter a closed wardrobe with talismans on the outside of it. They make Naerim open it to reveal a man hidden inside – presumably a dead man as he falls out of the wardrobe on top of Naerim without a word. Of course, everyone is shocked and runs off, leaving Naerim alone in the church with the dead body. As luck would have it, though, it isn't a dead body but a vampire, and he finds Naerim delicious.
After taking a few licks of Naerim's wounds, she kicks him off of her and takes off back to where the class is staying, but even as she escapes the church, she finds that a red thread now trails out from her wound, seemingly to nowhere and she is the only one who can see it. However, it's not clear what the thread is until the man appears on the balcony of the place Naerim is staying. She realizes that the man, named Vlad Fetechou, is a vampire and because he drank Naerim's blood, a witch, he has now become her servant with a collar and red string that ties them together. If Fetechou drinks enough of Naerim's blood, he will eventually become human, and their pact as servant and master will be broken, but will Naerim survive long enough to help Fetechou? Does she even want him to become human in the first place?
