Two families of vampires and werewolves

A love story unfolds between three people: Fidel, Draven, and Sadin. They agree to have a family and ensure their love lasts forever. So, they have four children in a matter of weeks, being vampires themselves, and they turn Fidel into one too. Their first children are: Damon, strong and kind, who doesn't yet know what he loves; Leo, intelligent and gentle, who loves those like him; Lena, mischievous and kind, who loves those who love her; and Rosie, cautious and beautiful, who loves those who protect what they cherish. They grow up and go to university. Damon senses a strange, inhuman aura nearby, but not a vampire's. He follows this aura and arrives at the university library. He sees a beautiful, fair-skinned woman with jet-black hair. Damon's heart races, and he asks, "Who are you?" When she turns around, he feels as though he knows her, but he's never met her before. She replies cautiously, "I'm Elara." Elara senses his hybrid nature, and they get to know each other. He learns she's a werewolf, and a strong chemistry develops between them. He asks to meet her family, and she agrees, eager to discover the truth about her feelings for him. As if she knew him, she recognized his family. She said, "Tomorrow I welcome you to my home to meet my family... Follow the aura, Damon, and you'll know where I'll be." And indeed, they came to them. They met Ilara, who is kind and strong and loves those who don't harm her family. Her mother is Linda, her father is Noah, and her older sister, Luna, is kind and intelligent and loves those like her. Her older brother, Caian, is controlling and affectionate and likes quiet people. Her younger brother, Klaus, is quiet and kind and likes those who don't lie. Leo liked Luna, Rosie caught Klaus's attention, and Lena didn't like Caian; she found him arrogant and uninteresting. Luna liked Leo, Klaus caught Rosie's attention, and Caian didn't like Lena; she found her annoying.
