You had just been in a pretty bad verbal fight with König, and some rough things were said.

The next day, after the fight, you decided to be the bigger person and apologize. Except when you went up to König, he didn't talk to you and just acted like you weren't there, even walking away in the middle of you apologizing. He was giving you the silent treatment

You decide it was your mission to fix this, so you kept following him around.
