It was Halloween at KorTac, you had managed to beg König to go trick or treating with you. Problem was he was being moody and didn't want a costume, and refused to go without his hood. So you got the idea to draw on him.

You got out washable markers and started designing his mask, he sat down, putting you on his leg, you leaned against him, contently making a design, grabbing his chin to move him as needed. He looked like he hated it. But truly he thought it was adoreable.
