Since it was already late, Seo-jun told Rowan to head back to his room. He reminded him that the next morning would be hectic—they still had to finish fine-tuning both the outer and inner tires, which were finally ready for use.
After Rowan left, Seo-jun smacked his own arm in frustration.
All this chaos—every bit of it—was the legacy of Adrian Hanwick's foolish past, and now he was the one stuck dealing with the consequences.
Physically and mentally exhausted, Seo-jun went straight to bed. These days, he had moved back into the Sebastian Hanwick estate, since his workload was no longer as overwhelming as it had been during the early stages of building the business.
He slept deeply.
So deeply that he woke up later than usual the next morning—something that almost never happened. Sunlight was already flooding the room. Seo-jun quickly got up and noticed several servants standing neatly in the corner, waiting for instructions.
Today was an important day: the product trial, to be witnessed by noble families from this kingdom—and even from neighboring nations.
Still groggy, Seo-jun let the female servants clean and prepare him. He was keenly aware of how awkward and shy they became whenever their hands brushed against Adrian Hanwick's muscular body—a figure famous for its undeniable charm.
Feeling a bit mischievous, Seo-jun deliberately winked.
The result was exactly what he expected—the servants let out small, suppressed shrieks.
At that moment, Margaret entered the room to check if her son was ready. She immediately frowned when she saw how slowly the servants were moving.
"Hey, what are you doing? Hurry up!"
she ordered sharply.
The servants quickly sped up, drying Seo-jun off before dressing him and fastening Adrian Hanwick's accessories.
Once they finished, Margaret paused.
Her son's charisma was undeniable.
The servants couldn't stop praising him, smiling brightly as they admired their master. That only irritated Margaret further. She promptly shooed them out of the room with a raised voice.
Noticing how emotional his mother seemed today, Seo-jun gently placed a hand on her right shoulder.
"Relax, Mother. Don't let unstable emotions dull your beauty,"
he said lightly, but with genuine care.
The sweet words instantly brought a smile back to Margaret's face. Her energy returned at once.
As they walked downstairs, Rowan was already waiting. He even took their mother's hand—something he rarely did, given his habit of wandering the world purely for pleasure.
When they arrived at the garden in the back courtyard, nobles and members of the royal family greeted the three of them enthusiastically—especially once Seo-jun began explaining the strengths of his invention.
"The greatest advantage of this product is comfort,"
Seo-jun said confidently.
"These tires are made from solid rubber, so they don't require air. They significantly reduce shock, making them ideal for stone-paved urban roads. On top of that, they're far quieter than the wooden wheels used on conventional horse-drawn carriages."
He paused briefly, then continued honestly.
"Of course, every advantage comes with drawbacks. These tires aren't suitable for long-distance travel between countries, and they perform poorly on muddy or sandy terrain, where they can easily get stuck. That's why this product is designed specifically for urban use—so nobles can enjoy a smoother, more comfortable ride within the city."
With the explanation complete, the moment everyone had been waiting for finally arrived—
The product test.
Seo-jun felt a flicker of nerves. There were simply too many ways this could go wrong. But when he thought about all the time, effort, and risk he had poured into this moment, his confidence slowly returned.
With steady steps, he climbed into the carriage. The door was deliberately left open so everyone could see clearly—this product wasn't an empty promise. It was the real thing.
And the results were immediate.
Seo-jun's body barely swayed. The harsh jolting common with wooden wheels was almost nonexistent. Nobles—ever hungry for novelty and exclusivity—began shouting offers over one another, all of them directed at Rowan Hanwick.
At the same time, Seo-jun introduced a complementary product: a custom interior fragrance for carriages.
For years, long journeys had been plagued by an unspoken problem—the mix of sweat and overpowering perfume favored by nobles. Instead of comfort, travel often became nauseating. That irritation was exactly where this idea had come from, and Seo-jun chose to debut it directly to the upper class.
The reactions were mixed.
Some frowned, finding the scent too fresh, too unfamiliar. But just as many were intrigued. Even Princess Victoria herself showed interest. The flatterers who had initially scoffed at Seo-jun's products suddenly rushed to place orders as well.
That day's profits exceeded all expectations.
Orders surpassed one hundred units.
Seo-jun, who had been riding the high just moments earlier, suddenly went quiet. He quickly stopped Rowan, who was still accepting orders nonstop.
Rowan looked startled.
"Why, Brother? Don't we have enough materials for five hundred units? Why stop now?"
Seo-jun answered calmly, but firmly.
"A new product must have limited production. Quality is everything. It's better to sell fewer units at a higher price and keep them flawless—than to mass-produce and disappoint. Once your reputation falls, it's over."
Rowan immediately nodded.
"Ohhh… I get it. Got it! Quality first!"
Raising his voice, Rowan officially closed the orders at one hundred units.
Several nobles who were turned away erupted in anger. Insults flew freely, targeting Seo-jun's products. But Seo-jun didn't flinch.
He stepped forward and spoke with a composed smile—never condescending, never aggressive.
"To our esteemed customers," he said gently, pausing for effect.
"Especially you, my lovely lady at the far end."
He bowed slightly and kissed the back of the noblewoman's hand with perfect courtesy.
"This limitation exists solely to preserve quality—so that what you receive matches exactly what we presented today. Once the first batch is complete, a second order phase will open. So please be patient—there's no need to lower yourselves through anger."
His voice was calm, yet commanding. Every gesture, every expression, was flawlessly controlled.
The Casanova had done it again.
No one dared argue after that.
