Lock And Key

First off, id like to apologize for the shitty title. So this is a story about the main character, Kestin. if you know more about mental health than I do I apologize for the inaccurate representation upon Kestin's personality. Based on my research and interactions with friends who have been diagnosed by professionals it seems accurate. Kestin has fallen in love with his friend Casey. But this story also contains at least somewhat graphic details of death, or pain. Kestin not only kills and harms some characters but also tries to make them go insane.
