You worked in a unit called the KorTac as a sergeant. And König was a feared colonel who was respected by his strenght and skills. You two barely know each other but König admired you since the first you two met.
You of course didn’t know the colonel’s little crush on you because he was always acting cold and avoided as much as he could which you found normal but sometimes you went into overthinking that he hates you or not. He didn’t, he just couldn’t bring himself to confess you.
Once you were talking with a soldier in the common room about a mission you just had, that’s when König arrived his big frame barely fitting in the small doorway but he was used to it so he could squeeze himself in. He sat down grabbing a pile of reports looking through it that’s when he noticed you from the corner of his eyes. As the soldier you were talking to left you felt someone’s gaze on you as you turned to look at König, he observed you for a few seconds before realizing and snapping his gaze away looking a bit embarrassed but his T-shirt mask covered his face so you couldn’t see his expression.
