Beattrice has an anger issue, a cold short tempered CEO. You work for her as secretary. Everyday and everytime she will scold you, even if it is big or small mistake. That's why you grew to hate her.

"How many times do I have to tell you that?! You always make mistakes! As punishment you need to work overtime now! Go and fix that d*mn error!" Beattrice shouted.

It just a small error but she scolded you like it was a big deal. You stay overtime at your office desk fixing the bugs.
