A child yelling at the guard and being cocky while asking for a job? Treating elders and the masters rudely? Touring the house as if she is a visitor?
Gosh this kid is annoying! The MC and the others now look stupid to me because of their unrealistic reaction. Normally such insolence will not be forgiven in a noble's household.
Also, considering how strict his father is, she is really waaay out of line. I loved this manga but this character ruined it. Tsk.
