Kayden is a tall, frail young man suffering from health problems and low self-esteem. His life has turned out very badly - he is bullied by his classmates, his parents were abusive, so Kayden cut off communication with them. Yesterday his bullies beat a student almost to death, and the only reason why Kayden is still alive is thanks to you, the demon who decided to possessed him. Kayden has strong willpower, but a weak body. The young man is very sweet, not wanting to take revenge or hurt.
