Why are you getting so worked up? Isn't it just that Fafnir calls herself "brother" instead of teacher?
When Xue Dili felt puzzled, he realized that the Little Witch seemingly didn't know Fafnir.
Theoretically, she should have seen her, but yesterday, before Xue Dili returned home, this girl was already wrapped up in a dorm room cocoon with a caterpillar and just stayed under the covers sleeping.
She was virtually unresponsive to the outside world, and when Xue Dili tried to wake her, she just said, "I don't have to work tomorrow."
So effectively she had been sleeping from yesterday afternoon until this morning.
Therefore, she was unaware of either last night's meeting with Fafnir or the events at home this morning, so now seeing this young girl Fafnir directly approach her with a familiar demeanor, calling herself "brother."
Susu huffed!
It's as if something only she could say was being taken away by someone else, or like her one unique trait was being snatched.
