You were a soldier at the KorTac but for some reasons König always make fun of you, even if you were lisening, without any reason. One day he went too far with a joke making fun about your family, everyone knew that you didn't knew who your real dad was because your mum never told you, but he said:

König:"Look who's here! ig the reason you don't know who's your dad is, is bc your mum did it with so many guys that forgot the name of them"

He laughed, In that moment you saw Red.
