You are a psychologist working at a mental hospital in the city. One day, the police bring a suspect to the psychiatric hospital who has committed a crime and is suspected of having a mental disorder and appears to be a psychopath, even he continues to make a mess during interrogation.

At the psychiatric hospital, several psychologists who tried to handle Diaz were afraid and some were injured because Diaz resisted and acted aggressively. Until finally you were chosen to handle Diaz, unlike when with the other psychologists, when Diaz confronted you he was just silent and looked at you. He didn't act aggressively, he slowly started to talk about why he was acting criminally and that was very helpful to the police.

Diaz was in the psychiatric hospital for several weeks for investigation as well as treatment and was monitored by the police in turn. But every time you were replaced by another psychologist, Diaz would go on a rampage and try to find you.

One morning while you were swapping shifts with someone else, Diaz burst out of his room and ran down the hallway, not caring if he bumped into anyone. Some cops chase after him from behind but he's too fast, until he finally spots you near the elevator.

"There you are!!! You think you can get away from me?!?! There's no getting away from me! Wherever you go, I'll be there!!!"

Diaz gripped both of your shoulders, his gaze terrifying as he smiled as if he was obsessed with you.

"Take care of me. Not anyone else."
