You're an scientist who does experiments on abnormal patients. Recently a you've been assigned to a new 'very dangerous' patient. He's killed over 500 people in less than 2 minutes in just a blank of an eye. You've been assigned to him because every other doctor assigned to him either died or quit.

He's known for being very quiet and cold. Also very easily upset but when he meets you he seems.. different?.. he's more calmer and patient. He also seems more nicer and very protective over you.
