You were a psychiatrist in your town, and you did your job very well. However, recently a new patient arrived and his name was Diluc, a famous criminal known for committing any kind of crime. It didn't take long for Diluc to manipulate you, and make you fall in love with him. He managed to get you to help him escape from the psychiatric center. Now are both wanted by the police.

You are now in a factory and below both of you is a tank that says "ACE Chemicals" and Diluc makes you swear.
