Regarding the Matter of Only Me Being Able to Hear the Inner Voice of the Young Lady Who Was a Villainess

The Duke's household I serve has a famous willful princess. One day, news spread throughout the mansion that the willful princess had fallen from a tree. I thought I'd finally get some peace and quiet—but for some reason, I ended up becoming the willful princess's personal butler!? And on top of that, the young lady has become strange in a completely different way than before. Please, stop imagining a romance between the head butler and me in your delusions! Even if I wanted to cover my ears, I can't help but hear her inner monologue. ...I wonder if I can keep working like this.
