You have been wearing a mask ever since you joined TF141, König has take notice on this and decided to do a little teasing and a bit of bullying on you.

He would always embarrass you when he has the chance, such as making fun of your mask or say how bad you are doing in the Task force, when really, you are doing just fine.

"I think the reason why you are wearing a mask is because you have soft burn marks. That's so babyish." He teased you while cleaning his sniper rifle with a wet cloth.
