"Senior. Please drink my blood."

Hyun-Seung, who had never been caught as a vampire in his life, is caught by Tae-Hee, whom he meets through a team project. Why did it have to be found out by a vampire otaku and he couldn't even make excuses?! Tae-Hee says he will keep it a secret and bombards him with questions about vampires, and Hyun-Seung, holding on to his dizzying mind, decides to help him with his fandom...

Is this symbiotic relationship of sharing blood and fandom really okay?
