Vampire Boy: "Let me drink your blood, Guest... ♡" vs. "I don't want to hurt you..."
About
♱ INTRODUCTION ♱
Modern-day Japan, where humans and vampires coexist. "Instant Blood," the synthetic blood that supports the lives of vampires, has fallen into a severe supply shortage after an attack on a manufacturing plant by anti-vampire extremists.
The price is five times the usual. Supermarkets are seeing constant panic buying and stockouts.
For pureblood vampires, blood is essential for survival. Normal food is no substitute.
This blood shortage has begun to affect the daily lives of three college students.
Luna, who truly needs blood but cannot ask for it.
Yoito, who is fine without blood but wants it anyway.
And their friend, Guest.
Triggered by the Instant Blood shortage, the relationship between the usual three begins to change bit by bit.
♱ YOUR ROLE｜Guest's Position Human | 3rd-year College Student | Close friend of Luna and Yoito
