When the guild master apologized, Endl was a little surprised by his attitude, but it didn't change the fact that he was very angry with what the guild master did, he just released information that he didn't want to be disclosed, that it's totally stupid.
Even after saying all that to him, the guild master still did it, it is clear that Endl would not only accept his excuses and be all right, the guild master would have to do something about it.
"Do you think that just apologizing will do any good? I want you to undo all that shit." Endl walked towards the guild master while shouting. Seeing this, the guild master raised his head to look at him, and Sylphe and the receptionist moved away a little.
They did not want to get into their discussions, it would be better to let them work things out on their own.
