The Underworld, Starting with Debt

After finding the school principal, Rikka Sumeragi, she learned that the school had a secret system that could help students relieve stress. With a try-it-out attitude, Mio Kato submitted an application to Rikka Sumeragi.

When Kato Mio applied for a "secret boyfriend" from the school principal, Sumeragi Rikka, she naturally looked at Ito Koshito's file and discovered that the person who ran so fast in school was none other than Ito Koshito. Excitedly, she contacted Ito Koshito to help her train!

…………

At the private St. Hua Girls' Academy, when Ito Kozue arrived, Kato Mio had already begun warming up.

Since it's Sunday, almost all the students are not at school, even Tsubakizono Nina, who is competing in track and field with Kato Mio, has gone home.

As for why Ito Koshi knew that Tsubakizon Nina had gone home, it was because Tsubakizon Nina had messaged him yesterday, inviting him to hang out.

……

"Oh hi, Ito-kun!"

From afar, Kato Mio spotted Ito Koshitoki arriving at the entrance to the playground and excitedly sped up to run towards him. Ito Koshitoki stopped and waited for Kato Mio.

When Kato Mio came in front of him, Ito Koshitoshi carefully examined his "girlfriend" for the day.

Wearing a dark red tank top and tight-fitting leotards, Kato Mio showed off her slender and graceful figure.

The tank top clung tightly to her toned upper body, outlining an alluring curve, as if drawn by a master painter's brush. Meanwhile, the tight-fitting gymnastics pants clung to her firm, full breasts, outlining perfect curves, like a flawless sculpture bestowed by nature.

During the long run, Kato Mio's face and bare, slender limbs developed a bronze hue from frequent exposure to the sun, creating a striking contrast with her fair skin hidden under her clothes, exuding the vibrant energy of a sporty young woman.

Because she had just exercised, Kato Mio had a thin layer of sweat on her body. This fragrant sweat made her skin look even more alluring, like a thin layer of dew clinging to her firm and smooth abdominal muscles, shining with a charming halo in the sunlight.

"Tsk tsk, even more handsome than in the photos! Ito-kun." Kato Mio raised her pretty face, brushed her hair which was stuck together with sweat, and looked at the tall and handsome Ito Koshito in front of her.

"And the muscles are amazing!"

"So how are you feeling?" Ito Koshitoshi asked with a slight smile.

Kato Mio said with a grin, "It's very good!"

"Please take good care of me, Kato."

"Oh, since we're 'couples' now, just call me Mio! Tomo~-kun~"

"Then, Mio, please take good care of me."

"whee……"

After the two got to know each other a little, Kato Mio couldn't wait to urge them on.

"Zhi-kun, hurry up and change your clothes, then run with me! The previous runs were just the beginning to get me going!"

"it is good……"

…………

The sun gradually rose high in the sky, its golden rays carrying waves of heat that swept across the land.

"Uh-huh——"

In a shady corner of a building on the playground, Kato Mio and Ito Koshitomo had been resting for quite a while.

Kato Mio picked up a water cup she had brought with her, filled it with water at a suitable temperature, and took a sip. The cool water flowed down her throat, like soaking in a clear spring on summer, or like snow melting in her mouth, instantly making her feel incredibly comfortable. She let out a soft moan.

"That was exhilarating! Running with someone is definitely more enjoyable than running alone!"

Stretching her body, as if every cell in her body was cheering with joy, Kato Mio couldn't help but sigh.

"Haha~"

"Running with someone creates a competitive mindset, which can improve performance. It also naturally coordinates the pace and breathing of each other. This synchronized rhythm can sometimes bring a unique sense of collective pleasure."

"Hehe...I see."

Wiping the beads of sweat streaming down his forehead, Ito Koshito stared intently at Kato Mio in front of him.

"Miyo, is there anywhere you'd like to go today?"

"Hmm...it doesn't seem so..." Kato Mio touched her lips, thought for a moment, and shook her head.

According to the school principal, the "secret boyfriend" is someone who helps students relieve stress by doing "that kind of thing"...

Kato Mio turned her head to secretly look at Ito Koji, but their eyes met, and his refreshing and sunny smile came into view.

Kato Mio turned her head shyly and touched her slightly flushed face.

'If it's Zhi-jun... it's not impossible...'

Kato Mio unconsciously fantasized about being forced beneath Ito Kozue by his well-developed muscles and tall stature...

Her small hands were slightly curled up, her fingertips touching her cheeks. The slightly hot temperature made her pretty face blush even more.

"Mio, Mio..."

Ito Koshito leaned closer to Kato Mio, staring at her with a puzzled expression. 'Why did Mio turn like this after just one glance at me? Does this ring have some other function?'

Her beautiful eyes were misty and dreamy, and she covered her flushed face with her hands, fidgeting shyly. Her cherry lips parted slightly, and her breath carried a faint minty scent.

The sudden sound startled Kato Mio awake. 'Ugh!!!... It seems next week's track and field competition is really putting a lot of pressure on me.'

Thinking about how she's been doing more handicrafts than ever before, and how she gets feverish in front of Ito Koshitomo, Kato Mio felt a little ashamed.

"Hey... Zhi-kun, we're 'couple' today, right?"

"Yes!"

Kato Mio stared blankly at Ito Etsuto, her spirited eyes gradually welling up with tears, and a hint of spring crept into her brows.

"Will Zhi-kun listen to me?"

Remembering the instructions from the royal rokuka, Ito Koshitomo nodded solemnly.

"Of course, the job of a 'secret boyfriend' is to serve you wholeheartedly."

Kato Mio grasped Ito Koshitomo's large hand with a charming smile.

"Zhi-kun~ come with me."

Seeing Kato Mio running ahead, Ito Koshino followed her, pulling her to the front of the changing room.

"Zhi Jun, wait a moment, this isn't our destination. Let me get something."

Releasing Ito Kozue's hand, Kato Mio smiled and said that this was their school's track and field team's locker room, where many of the other team members' private belongings were hidden, so she couldn't bring Ito Kozue inside.

The main issue is surveillance. Although the Royal Six Flowers are there to protect her, the surveillance footage will definitely not be leaked. However, if she can't resist and leaves some traces with Ito Koshino in the changing room, it will be troublesome if more students discover this secret system of the school.

After all... the "secret boyfriend" system is the school's biggest secret, and the fewer people who know about it, the lower the risk of exposure.

…………

"Clang-crack-"

Pushing open the heavy door, Kato Mio led Ito Kozue into the rooftop of the private Seika Girls' School.

"call--"

A gentle breeze blew in, carrying the pulse of the city and the fresh air from afar. It soothed their slightly tired bodies after their run.

Before you lies a vast open space, surrounded by towering iron netting, seemingly isolated from the outside world, with only the sky stretching endlessly, giving one the illusion of free flight.

"Zhi Jun, come over here, it's cooler here."

Leading Ito Koshitoshi to a shady corner on the rooftop, Kato Mio found the backpack, took out a brand-new camera, and handed it to Ito Koshitoshi.

"Is this a camera?"

Carefully accepting the camera, Ito Koshito curiously examined the obviously expensive-looking device.

Kato Mio patted Ito Koshino on the shoulder and said with a grin.

"That's right! Zhi-jun, come take a picture for me!"

Chapter Sixty-Six: The Photo on the Little Blue Bird

"Take photos? But I've never used a camera before!"

After fiddling with the camera in his hand and looking at the numerous buttons on it, Ito Koshito felt somewhat embarrassed.

"Let me teach you~" Kato Mio took the camera from Ito Koshitoki's hand, sat on the ground leaning against the wall, and patted the ground next to her.

"Come, sit here, I'll explain how to use it to you."

"oh oh."

…………

With Kato Mio's brief explanation, Ito Koshitoki gained a basic understanding of the functions of those buttons, at least enough to take simple photos and delete them.

"Alright, you should now have a basic understanding of the camera's functions."

"Hey~"

Handing the camera back to Ito Koshitoshi, Kato Mio jumped up, straightened her body, put her hands on her hips, and said with a faint, charming smile.

"Zhi-kun~ Come take a picture of me!"

"it is good!"

Standing up, Ito Koshitoki looked at Kato Mio with his camera in hand.

With everything ready, Kato Mio looked around. The empty rooftop didn't offer many good spots for taking pictures.

"Hmm... let me think, how should we film it?"

"Alright, let's take a stretching photo first to get a feel for it!" Kato Mio made the decision, clenching her fist and slapping her other palm.

"Zhi Jun, come this way."

Stepping into the sunlight, Kato Mio stretched her body, then interlaced her fingers, palms down.

Strong, toned thighs straighten, rounded buttocks raised by years of exercise, back bent forward, curves showing a beautiful arc.

A perfect standing forward stretch perfectly showcases Mio Kato's graceful curves.

"Zhi-kun~ Hurry up and take a picture!"

After glancing at Kato Mio's alluring figure a few times, Ito Koshichi picked up his camera and started snapping photos of her.
