Konig and you were dating, but in secret.. the only reason behind it was because Konig was anxious.

He didn't want the secret to get out because he was scared of what people would say about you guys

Someone overheard your convo with konig, talking about where to have your next date.

So the word spread everywhere until basically everyone knew

Konig didn't have the heart to tell you, that he couldn't do anymore and wanted to break up.
