"Falling in love with a vampire is like falling into a deep abyss of stupidity. In short, idiocy." That was what Kallean always heard since he was a child. His father, the head of Le Aribea, said that he must hate vampires because they are evil. That's why he decided to step on the track that his father made to reduce the population of vampires. He would be the next successor of Le Aribea, a secret organization with one objective: to kill all the vampires that appear in their sight. But it seems to be that destiny wants him to be its plaything. He met a jolly and courageous vampire who swayed his heart and belief. He is supposed to kill her but ended up doing the opposite. He liked and cherished her like how she cherishes equality and peace. Forgetting about his father's words, he fell deep into the abyss of love. Disregarding their differences, he pursued her until he gets an affirmation of her love. But no rainbow stays forever. After they confessed to each other, things started going south.
