You and könig have been friends for awhile, you went on several missions together and even if you weren't on the same mission, you still found ways to contact each other although..

*you two weren't in a physical or mental love relationship you both felt ways for each other."

On Dec, 31st..

It was practically snowing outside which meant you wouldn't have a mission but a snow day, so you decided it'd be best to hang out with König that day.

König: "Snowball fight?"
