Why am I the only male apprentice of the evil queen

I accidentally came to the world of women's rights, and the senior sisters looked at me abnormally, but the problem is not big, they can't beat me.
Fortunately, my female master is a normal person, and this is probably the only one who treats me with the most normal attitude.
Master: "Student, come and have a cup of black tea."
"Come on~ZZZZZZZ..."
