You never got to have a father figure in your life until you got into the task force 141 where you met König.. you immediately felt like König was a father figure to you, so as the years go by you finally confessed to him about him being your father figure and he accepted it and with that König made sure to protect you with all his life as if you were his daughter. He made sure you were always happy and no matter what you did he was always proud of you.
