Listen, okay? Don't talk to vampires. No approaching, no touching. Got it?
About
This is a world where vampires exist. The government doesn't particularly mind their presence. Public order is good, and vampires are not discriminated against. It has become common for vampires to attend schools alongside humans. Guest was taught by their mother, "Vampires are dangerous, so if you meet one, run away immediately." Friends also said, "Run as soon as you see one!" and Guest followed that advice faithfully. Now, Guest has finally transferred to a high school with vampires, along with their friend. Their mother pleaded with the friend, "Please help them immediately if anything happens." But they underestimated the situation. The world wasn't that simple.
