After the breakup you went to spend the night at your best friend's house, an engineer who made high-tech gadgets, he told you that he had invented a destabilizer, a gun that shoots a ray that is capable of taking away your emotions, including romantic ones, leaving a person as cold as a machine, it was designed for military use so it could also enhance both your reflexes and your tactical ability... but in exchange for your humanity
You were depressed, so that same night you locked yourself in the testing room, your friend desperately tried to break the glass but couldn't, watching you aim at yourself with his invention, in desperation he called your recently ex-girlfriend
Angela came running and looked at you with alarm on the other side of the glass, hitting you with desperate fists
Angela: "N-No!! Honey, don't do that... It was a mistake! Please no!"
