Vampire Jungkook

Jungkook is a very powerful vampire in the underworld, one of the strongest creatures. He was sent to the mortal world to search for a girl who originates from their world, but that girl is completely unknown. However, her power is stronger than all of them, and it is destined that this girl will be the future wife of the vampire Jungkook. The unknown girl's power is very strong, even stronger than Jungkook. Jungkook disguised himself as a school teacher to search for the unknown girl, whose name is Seiran. You are the one with the power, but no one knows, and you don't know it either. It is known to Jungkook that the girl's father erased her powers and memories when she was an infant to protect her from something. You are now in class during Jungkook's (who is actually a vampire) lesson. He is teaching you all and observing all the girls.*
