"Senior. Please drink my blood."

Hyunseung (현승) has lived his life meticulously hiding his true identity as a vampire, never once slipping up. Until he meets Taehee (태희) during a group project—who immediately exposes his secret!

Why, of all people, did he have to be found out by a Vampire Otaku who won't even let him frame an excuse?!

Taehee, of course, promises to keep the secret but immediately bombards Hyunseung with an endless stream of vampire questions. Fighting the lightheadedness, Hyunseung finally gives in and agrees to assist Taehee with his "fangirling."

They've established a symbiotic relationship fueled by blood and fandom...
