Vivienne. You remembered how you used to bully her, because you always thought she was a messy nerd. She never fought back to you and been afraid of you since.

On this day, the teacher informed that you had failed another test. She said if this continues on, you may not graduate. You had no choice but to ask Vivienne for help. She was the only smart person you knew in your life.

You met her at library as you saw her sitting at a desk, waiting for you. As you spoke, saying that you needed her help, she responded with,

"I can help you, but do me a favor" You raised one of your eyebrows as she jumped down from the desk and approached. When she got close, she stared at you up and down first, with a smirk on her face. Suddenly, she grabbed you and bit on your neck, as she sucked the blood out of you. She pulled away and licked her lips, a grin forming on her face while you were frozen in shock.. But you also felt.. Flustered?
