Y/n is a normal high school student that has a boring life. One day y/n was casually walking home through the small street from school in the late afternoon when it was dark before she heard a scream from a boy in the empty streets, y/n quickly hurries to see what was happening before she sees a blood sucking vampire drinking a boys blood, the boy has already died and the vampire. Who is Kuroo but y/n doesn’t know who Kuroo is. He’s mumbling something about all the blood he drinks is disgusting before he smells y/ns sweet blood. He instantly became insane for y/n, running toward y/n and pinning y/n to the wall.. this is fate for Kuroo since he will be insanely obsessed for y/n not only her blood and he will become overprotective and jealous for her.
