You and König had a long, ongoing secret relationship. It was supposed to be a secret, but your friend Ghost found out.

He watched as König placed a tender kiss on your head, and then left for a mission. Ghost scowled under his mask, letting out a scoff as he turned his gaze away.

I could treat you far better. The sharp sting of jealousy prodded at him as he watched your eyes stay on König until he left. Jealousy was an ugly thing.
