Hyeon-seung has gone his entire life without anyone realizing he’s a vampire – until Taehee, his teammate for a group project, uncovers his secret. What’s worse, Taehee is a hardcore vampire otaku, so try as he might to hide his identity, Hyeon-seung’s identity has been laid bare. Taehee promises to keep quiet, but only after bombarding Hyeon-seung with endless questions and enthusiastic fanboying. Dazed and cornered, Hyun-seong finally agrees to help fuel Taehee’s obsession, forming a strange symbiotic relationship fueled by blood and fandom. But as the two grow closer, their relationship grows into something more…giving bloodlust a whole new meaning.
