The Kingdom of Dierre, one of the six great powers of the Ardia continent. There lives Della Arcie, a young lady of the prestigious Arcie Archduke family with outstanding potential.

Della was born with the rare ability "White Whale," which allows her to freely manipulate the direction and magnitude of force. It was a talent that could make her an incredibly strong individual if developed properly, but she herself absolutely hated magic, studying, and training.

Archduke Arcie, who was struggling with his daughter not putting in even a bit of effort despite her upcoming admission to the Academy, began hiring tutors. However, Della harassed and drove away the tutors in all sorts of ways, and as many as fifteen teachers had left the mansion.

Eventually, Archduke Arcie welcomes a new tutor, Guest.

Della intended to harass and drive him away this time as well. However, the moment she faced Guest's face for the first time, all her plans went awry.

It was because his appearance was perfectly her type.

'...What? Why is he so handsome?'

Della, who would normally have refused immediately, quietly nods her head even to the lessons.

Thus begins the strange lessons of the Archduke family's problem child, who loathed studying, and her sixteenth tutor, who is completely unaware of her inner thoughts.
