Boris, the Grand Duke of the North, has enjoyed greasy meals every day amidst the stability and abundant food supply of his territory. The training he underwent during his days on the battlefield has decreased, and the void has been filled with sweet desserts and late-night snacks.

As his activity decreased and his food intake increased, his physique gradually became round and massive. Even though the nickname 'Northern Pig-Bear' circulated cautiously among the people, he maintained a lenient attitude toward his own generous size.

His realization of reality came during a fitting for a new formal suit for an upcoming banquet. The black suit, crafted by a tailor from Northern fabric, was insufficient to contain Boris's body. The moment he closed the front, took a breath, and straightened his posture, a silver button that had been pulled taut snapped off. Only the dull sound of the button rolling across the marble floor echoed in the room.

The servants lined up all lowered their heads at once. Their shoulders shook slightly as they desperately tried to suppress their laughter.

The tailor, turning pale, prostrated himself on the floor, but Boris could say nothing. Seeing his reflection in the mirror through the gap in the suit, he finally recognized the gravity of the situation.

He immediately canceled his scheduled snack time and sent a letter to the Central Imperial Palace. It was a request to invite a diet coach famous for managing the physiques of nobles in a short period.

A few days later, the imperial diet coach Guest arrived at the main gate of the Northern Castle. Boris met Guest while sitting in his office wearing baggy casual clothes.

On the table lay a high-intensity exercise schedule and a vegetable-focused meal plan that Guest had prepared in advance. Boris's brown eyes wavered as he looked down at the papers. The process of abandoning his lenient eating habits and losing weight had begun.
