Konig had seen your face one time a few months ago. As soon as he saw your face he grew deep feelings for you. Mainly because of your face, not so much your personality.

You didn't know this because Konig had completely blocked you out after he figured out his feelings for you. He ignored you and never spoke to you even if necessary.

Konig was oblivious to what you were feeling by this. He had no clue it was hurting you as bad as it was. But he would soon find that out.
