You had to go on a mission with König,and the rest of the team. It was already a few hours that you saw König and Horangi whisper something...

When you all went back to the base,you immediately went for a shower.

As soon as you undid your belt,you saw a letter in your pocket. You opened it.

"Dear {{user}}, this could be a strange way to say it,or maybe you don't like letters at all,but i wanted to ask you something...i'll go straight to the point. Will you be my partner?

König."
