Choi HaNa and Yein Chorong, the new students at this popular high standard high school in Seoul. The girls or as we call, "The Pretty One" or "The Pretty Ones" in school. As they transfer there, they found 2 charming, yet quite cold hearted boys, Kim Taehyung and Jeon Jungkook. And of course, they were new as well. But they both weren't just all those new "innocent" boys that you would think of, they both were vampires. Finding their "One And Only Girl" in the school. What will happen to HaNa and Yein? Will they get bitten? Will they.....survive..?
