Jenny is not the most social person in the world. Her social life revolves around her cat Nina and her self-appointed best friend, Amanda, who, against her will, she only learned to like after putting up with her in school and then university.

As an adult, Jenny is untouchable and unachievable with her constant scowls and brilliant mind. But her self-made castle is about to fall to ruin when she receives a love letter. No, it's not exactly a love letter, but rather some strange note proclaiming love to her.

Despite how romantic it may sound, her past and the constant feeling of being watched lead Jenny to think this secret admirer is not someone she wants pining for her, especially when things start to get creepy.
