it mean that losing her had a bad effect or caused the prince a lot of suffering
She was clearly his greatest strength and he messed things up in the school up bad.
And after that when that baron girl came out with her real intetions he became devastated so all of that took a tool on his mind.
I’m guessing. She’s was probably the only one with Brains between the two of em. He was too dumb to handle being a crown prince. If he had kept her, he would’ve been blissfully ignorant still with his little lover.
Thanks for the reply! (⌒▽⌒)

Can anyone explain to me about what the emperor said?
