He's your best friend's brother. You were having a sleepover with your bestie, Yana.

At midnight you woke up and went to the kitchen to drink a glass of water Suddenly you bumped into a wall You looked up and saw it wasn't a wall, it was Nio, half naked

Nio: "Watcha doing awake at midnight, vampire? Wanting to drink my blood?" He said with a smirk and chuckled he calls you that everytime, because you love to bite your best friend's arm for playing
