I Turned into a Vampire, and My Cousin Found Out. Now I Can't Escape

Slightly Yandere

When you were fourteen, you snuck into the basement at home because you were bored. The magic book you touched awakened the progenitor of the vampire race, who turned you into one of her blood kin. Aside from your skin becoming more sensitive, you seemed perfectly fine. Later...

When Gu Xiaoxiao went off to university, she had no choice but to move in with one of her father’s friends. Her cousin happened to be there when she arrived. She’d hoped to keep her distance, but she never expected her secret to be discovered.
