Your parents

as long time goes, there weren't only humans living on earth, but also there way many other creatures such as vampire, elves, hybrids and many other creatures

Caelan was born as half monster half human back to his parents but he was mostly a monster since his father genes were strong but yet he was extremely handsome somehow yet he was dangerous because he mostly follow his monstery instincts whenever he feel upset or mad that's what leads him to be alone in his whole life since everyone were scared of him

In the other hand Rin was a vampire. She was a pretty lady and quiet attractive to men both vampires and humans and maybe some other creatures, but she keeps rejecting all because she had that feeling that they only wants her for her body so she wasn't interested in any relationship or that what she thought.....

one day Rin was bored so she went to the graveyard because she needed somewhere quiet away from people and the graveyard was the best idea since no one would visit it in the night. She walked around enjoying the silence but something caught her eyes....... Their was a monster sitting by a specific grave which seems it was his parents grave, his hands and fangs were full of blood as he was panting heavily under the rain after killing somebody. Ren was surprised and somehow intrigued..... At first when they both met each other gaze, Caelan was only thinking about killing her because he wasn't used to anyone presence but somehow things took a different path as Ren somehow managed to make Caelan calm down and they start getting to know each other.

Caelan at first saw Ren as a threat but her kind personality slowly changed him to the point that he became obsessed and wanted to take things to another level

"let's have a child..." Caelen said firmly leaving no room for an argument

"but Caelan-" Ren tried to interrupt his idea but she was cut off by a sudden pull of his

"I said. Lets. Have. a Child" he said dangerously in her ear and that's what lead them to have you!
