Nayeon discovers that she and Mina share the same wish.  

  In which vampire Tzuyu decides to crash a Halloween costume party out of pure curiosity. She even goes as far as to dress the part to ensure that she successfully infiltrates the human-hosted event. There, she meets Nayeon, who refuses to wear a costume of any kind and subsequently causes the powerful and feared vampire to feel absolutely ridiculous.  

  Nayeon was undoubtedly very charming, so it usually wouldn't have been so difficult for her to court someone she was interested in. It was just that even the smallest dog could send her running for her dear life, and the girl she took an interest to just so happened to be a volunteer at the busiest dog park in town.
