Everything Begins With a Debt in the Hentai World

"Mmm…"

In the quiet, secluded park, a black sedan was parked under a dilapidated streetlight. Inside the car, its owner was lounging against the seat, feeling a bit bored.

Suddenly, a tall boy in black approached from a distant alley. The moment his presence registered, Ito Yoshito pressed the horn before turning on the headlights to catch the boy's attention.

"Tap~ Tap~~"

Reaching the driver's side, Ito Yoshito knocked on the window.

As the window slowly rolled down, the neat figure of Tsukishima Matsuo came into view, his serious expression firmly etched in Ito Yoshito's mind.

"Mr. Matsuo, thank you for coming to pick me up."

"Yoshito, get in the car first."

"Okay." 

———

On the bustling streets, various car lights and neon signs created a vivid tapestry of nighttime vibrancy. Following the flow of traffic, Tsukishima Matsuo tried to engage Ito Yoshito in casual conversation.

"So, Yoshito, how's it going with Kyouko at school?"

"Well... I've had to be cautious at school. I haven't really had the chance to spend time alone with Kyouko."

"That won't do! You've only come to my house once this week. How can you develop a relationship if you don't seek her out at school?"

Ito Yoshito felt a bit exasperated. It seemed that after just a week apart, Tsukishima Matsuo had become even more obsessed!

"Yoshito, I'm telling you, don't let Kyouko's cold demeanor fool you. Deep down, she loves that sort of charm…"

"Mr. Matsuo! Please focus on driving."

"Hey, don't interrupt me! Listen…"

...…

"Click!"

"Kyouko, I'm back!" 

Tsukishima Matsuo entered the house with Ito Yoshito in tow.

"Matsuo, you're back."

A pleasant, magnetic voice floated from the study, followed by the familiar sound of high heels clicking on the floor.

Ito Yoshito looked in and was momentarily taken aback. Tsukishima Kyouko was wearing the blue office lady uniform she often sported at school.

The form-fitting blue uniform accentuated her graceful figure. The mildly open V-neck revealed glimpses of delicate black lace edging, adding an alluring and mysterious touch.

Her black high heels elongated her legs, while sheer black stockings wrapped around her voluptuous thighs, radiating an enticing glow.

With her dark blue hair cascading down, it slightly obscured her fair neck and collarbone, lending an aura of mystique. Standing there with her arms crossed, she showcased her perfect curve, resembling a regal ice goddess surveying her domain.

Her narrow, expressive eyes sparkled with amusement as she gazed at Ito Yoshito, exuding an elusive charm that was both lofty and irresistible.

Standing at the entrance, Tsukishima Kyouko ignored her husband, Matsuo, her focus entirely on Ito Yoshito. She playfully waved a ruler, producing a faint crack in the air. 

"Ito boy, are you ready yet? Our study session is going to be quite challenging~"

Her voice was like honey, sweet and captivating, akin to soft silk delicately brushing against Ito Yoshito's eardrums.

Quietly, Ito Yoshito felt a surge of fervent anticipation build within him, radiating an overwhelming heat…

With a slight tilt of his head, he discreetly assessed Tsukishima Matsuo.

Faced with his wife's blatant disregard, Matsuo appeared somewhat irritated. He bent slightly, his body trembling with an unresolved anger, yet he could only gulp down his indignation, reminding himself of Kyouko's authoritative presence in their home.

Turning back to Kyouko, Ito Yoshito stood tall and confidently declared, "I'm always ready! Kyouko… no, Tsukishima-senpai!"

With a satisfied nod, Tsukishima Kyouko smiled more alluringly and pivoted on her heels, striding toward the study.

"Then follow me."

"Today, I will teach you how to arrange flowers. Flower arranging is an ancient art form that originated in China and Egypt, initially related to offering flowers in Buddhism. It is not only a decorative art but also a way of expressing feelings and cultural significance."

"Today… I'll start by teaching you how to appreciate the beauty of bougainvillea…"

...…

Gentle sunlight fell upon Ito Yoshito's fluttering eyelashes, resembling a butterfly ready to take flight.

Ito Yoshito awakened in the familiarity of his small rented room. Although he had "studied" late into the night, he sensed that Matsuo had listened in from next door without sleeping.

In preparation for his "secret boyfriend" duties the following day, Ito Yoshito decided not to stay overnight at Kyouko's home, opting instead for Matsuo to drop him back.

On the drive home, Matsuo was unusually animated, his chatter almost incessant as he sped, leaving Ito Yoshito drenched in cold sweat.

By the time they arrived home, it was already three in the morning. As Ito Yoshito stepped back into his small rental, he thought he caught a brief glimpse of a white nightgown on the second floor, but it vanished too quickly for him to be certain he had seen anything.

Katou Mio: [Yoshito-kun, have you woken up yet? Remember, we're going for our morning run!] (Read)

Ito Yoshito: [I know! I'm heading to Seika Girls' Academy now.] (Read)

———

After his last encounter with Sumeragi Rikka, she had shared the LINE details of his next client, Katou Mio.

Initially, Katou Mio felt immense pressure due to an upcoming athletic competition and often found herself distracted during training, which hindered her performance.

After speaking with Principal Rikka, she learned about a secret system at the school designed to help students relieve pressure. With a mindset of giving it a try, she submitted an application to Rikka.

Naturally, upon applying for the "secret boyfriend" program, Katou Mio reviewed Ito Yoshito's profile and recognized him as the exceptionally fast runner from school. Excitedly, she reached out to him, hoping he could help her train!

...…

At Seika Girls' Academy, when Ito Yoshito arrived, Katou Mio was already warming up.

Since it was Sunday, nearly all the students were absent. Even Tsubaki Shina, who was set to compete alongside Katou Mio, had gone home.

Ito Yoshito knew that Tsubaki Shina had gone home because she had invited him to hang out the day before.

...

"Hey there, Yoshito-kun!"

Eagerly, Katou Mio dashed toward him as soon as she spotted him at the playground entrance. Ito Yoshito stopped, waiting for her to reach him.

When Katou Mio was finally in front of him, Ito Yoshito took a careful look at today's version of his "girlfriend."

Wearing a dark red tank top and tight-fitting gymnastics shorts, Katou Mio showcased her long, slender figure.

The tank hugged her athletic body, outlining alluring curves as if it had been crafted by a master artist. The snug gymnastics shorts accentuated her perky backside, generating a perfect silhouette, reminiscent of nature's flawless sculptures.

Having spent extended periods running in the sun, Katou Mio's face and exposed limbs glimmered with a bronzed glow, contrasting starkly with the fair skin hidden beneath her clothing and exuding a vibrant youthful energy.

Due to her recent workout, a thin sheen of perspiration adorned her skin, enhancing its allure. The glistening droplets looked like delicate dew, clinging to her flat abdomen, shimmering under the sunlight.

"Wow, you're even more handsome in person than in the photos, Yoshito-kun." Katou Mio lifted her delightful face, playfully tousling the strands of hair glued to her forehead with sweat, admiring the tall and charming Ito Yoshito.

"Plus, those muscles are fantastic!"

"So, what do you think?" Ito Yoshito smiled slightly, inquiring.

Katou Mio beamed, "Really great!"

"Let's work well together, Katou."

"Come on, since we're 'couples' now, just call me Mio! Yoshito-kun~"

"Alright, Mio, I look forward to it."

"Ehehe…"

As they got to know each other, Katou Mio eagerly urged, "Yoshito-kun, hurry and change your clothes so we can run together! The few sets we just did merely ignited my enthusiasm!"

"Sure…"

...…

The sun rose high in the sky, its radiant golden light casting warm waves over the earth.

"Ah—"

In a shaded corner of the playground, Katou Mio and Ito Yoshito had taken a moment to rest.

Katou Mio picked up a water bottle she had brought, filled with perfectly temperatured water, and took a sip. The icy liquid flowed down her throat, reminiscent of a refreshing dip in a clear spring, or the melting of snow in her mouth, instantly bringing her immense comfort.

"So refreshing! Running together is surely more enjoyable than running alone!"

Stretching out, it felt as if every cell in her body was rejoicing. Katou Mio couldn't help but express her delight.

"Hehe~"

"Running together creates a sense of friendly competition, which can improve performance. Plus, it naturally coordinates our steps and breathing. This synchronized rhythm often brings a unique sense of collective joy."

"Ehehe… so that's how it is."

Wiping the sweat from his forehead, Ito Yoshito gazed intently at Katou Mio.

"Mio, is there anywhere you want to go today?"

"Hmm… it seems not…" Katou Mio pondered for a moment, then shook her head.

'According to Principal Rikka, the "secret boyfriend" role is specifically designed to help students relieve stress through a means such as this…'

As she glanced sideways at Ito Yoshito, their eyes met, and his refreshingly sunny smile flooded her vision.

Feeling a tad shy, Katou Mio turned away, brushing a hand against her slightly heated cheeks.

'If it's Yoshito-kun… it wouldn't be too bad…'

In her mind, fantasies of being pinned beneath Ito Yoshito—his strong muscular build, his towering height—began to unfold…

Her small hands instinctively curled, fingertips grazing her cheek's flushed warmth, enhancing her already rosy complexion.

"Mio, Mio…"

Ito Yoshito leaned closer, scrutinizing her with curiosity. 'Why did Mio get all flustered just from one glance? Could this ring have more functions?'

Her dreamy gaze contained a misty allure as she covered her blushing face, fidgeting slightly, her lips parting and closing, exuding a subtle minty fragrance.

A sudden sound jolted Katou Mio awake. 'Hmm!!!... Looks like next week's athletic competition really has me feeling a lot of pressure.'

Reflecting on her increasing anxiety about her responsibilities and her flushed reactions around Ito Yoshito, Katou Mio felt a pang of embarrassment.

"Hey… Yoshito-kun, we're 'couples' for today, right?"

"Absolutely!"

Katou Mio stared absentmindedly at Ito Yoshito, her spirited eyes moistening with unshed tears, warmth blooming in her cheeks.

"So, will you listen to me, Yoshito-kun?"

Recalling Principal Rikka's advice, Ito Yoshito nodded solemnly. 

"Of course, my role as your 'secret boyfriend' is to serve you wholeheartedly."

Taking his large hand, Katou Mio beamed as she replied, "Yoshito-kun~ come with me."

Following her lead, Ito Yoshito was drawn alongside Katou Mio as they approached the changing room.

"Yoshito-kun, wait a moment, our destination isn't here. Let me grab something."

Releasing Ito Yoshito's hand, Katou Mio smiled cheerfully. This was the changing room of their school's track team, containing private items of other team members, so she felt it inappropriate to bring him inside.

Primarily, since there were security cameras—while Principal Rikka assured her they wouldn't leak, she didn't want to risk leaving traces that might expose the school's secret system to more students.

After all… the "secret boyfriend" program was the school's biggest secret; the fewer people who knew, the smaller the exposure risk. 

...…

"Clang—"

Pushing open the heavy door, Katou Mio led Ito Yoshito onto the rooftop of Seika Girls' Academy.

"Whew—"

A gentle breeze welcomed them, carrying the rhythm of the city and fresh air from afar, soothing their slightly fatigued bodies after running.

Before them lay a vast open space, surrounded by tall iron fences that seemed to isolate them from the outside world. Only the limitless sky above provided the illusion of unrestricted freedom.

"Mio, come over here; it's cooler this way."

Katou Mio guided Ito Yoshito to a shaded corner of the rooftop, retrieving a brand-new camera from her bag. 

"Is this a camera?" 

Cautiously taking it, Ito Yoshito marveled at the expensive-looking device.

Giving Ito Yoshito a playful pat on the shoulder, Katou Mio cheerfully said, "That's right! Yoshito-kun, come help me take some photos!"
