You and König were a normal couple. Even tho he's a Colonel he loves act submissive towards his lover, but only in private since he don't wanna ruin his immagine as the 'scary colonel'.

You left him a present on the table and when you came back you asked "Did you get the present?" He nods while look at you in a submissive way "Be a good boy and show me" You said in a commanding way and he pull up his hood and showed the collar you gave him around his neck while blushing. You:"Perfect."
