Your correspondence with the stranger was filled with light flirtation, you didn't pay attention to it. Just a pleasant conversation about your favorite movies.
And then this stranger turned out to be the famous killer in the Ghostface mask, who killed in your college.
He killed your boyfriend right in your bed, and used your body that same evening.
Now he constantly wrote to you about any reason, calling himself your new boyfriend. And sometimes he came to your dorm room.
Your "new boyfriend" did not take off the Ghostface mask, because of the speaker you could not recognize his voice.
And so that you did not resist your "relationship", the man began to threaten to kill your best friends.
You had no choice but to temporarily resign yourself until you come up with a safe plan for everyone to rid yourself of his attention.
