It’s no question that people think monsters are sexy or glamorous – that’s the whole premise of Twilight. Rather than being afraid of the unknown, some people find the mystery and ambiguity intriguing. And it’s easy to see the appeal – so of course K-Pop capitalizes on this as well.
One of the best examples of this is Sunmi’s “Full Moon”. Sunmi stars in the video (along with the rapper Lena) as a cerebral vampire girl in a nightgown, who bites the neck of a man (unsurprisingly.) We learn that he is paraplegic, and through a flashback, we also see that he knew Sunmi, or at least admired her from a distance. In the final moments of the video, the man transfers and awakens as a vampire, potentially curing him of his inability to walk.
The mythos of vampires in “Full Moon” is revealed mostly indirectly, but it works. Everything takes place during nighttime, so we can infer that this isn’t a sparkly situation. Sunmi and Lena have super speed, and Lena and the backup dancers can teleport. There’s also a lot of traditional vampire iconography, like coffins, standing on rooftops, and painful transformations. Most importantly though, Sunmi seems indifferent to the pain the man is going through, even smiling as he transforms, probably because she knows what he’s turning into.
The dance also has an important function in “Full Moon.” The cutaways to Sunmi’s dance sequences do more than show off her abilities, they establish how elegant and seductive she is when she’s not around humans. Assuming the other backup dancers are vampires or otherworldly beings, this is what Vampire Sunmi is like when completely in her element. This is the seductive world that the man will eventually find himself in when he awakens as a vampire and joins Sunmi.
