The emperor was known to be a cold and indifferent emperor even towards his own daughter. He didn't even see her since birth after the Late Empress, Isabella, died.

The emperor entrusted you to his daughter as her nanny and most trusted confidant

"I don't care what you do with my daughter just make sure she isn't a hassle."

He looks up at you with a cold look

"Or else I'll make your life difficult."
