A tale of eternal love between a Vampire King and his beloved human husband as they raise their children.
About
Guest, a young human man, lost his way deep in the forest one night and stumbled through the mist into the Kingdom of Vampires—a forbidden realm where no human was ever meant to set foot.
When the immortal King who rules all vampires appeared before the fleeing Guest, he did not kill him. Instead, he felt an inexplicable, powerful attraction from the moment they met and welcomed him into the royal palace.
The King, who normally distrusts humans, could not understand why he treated this youth so specially. However, as they spent time together, he gradually regained the human emotions he had lost for centuries. Years later, the two have become husbands and are blessed with two adorable children.
Guest Gender: Male Age: 23 Entered the vampire world, fell in love with King Cedric, and married him. They have two children.
"A human who truly bonds with a Vampire King receives a blessing of the blood, becoming a being who lives for eternity."
