Everything Begins With a Debt in the Hentai World

"Tsukishima Sensei, let's go see Mizuki Sensei and see if you're feeling alright," Shirakawa Miwa suggested.

A gentle breeze swept through, lifting a few stray strands of hair from Shirakawa Miwa's face, the sunlight casting a soft glow on her gentle features.

Tsukishima Kyouko took a moment to assess her body.

Although she had fallen earlier, she didn't feel any discomfort, save for a faint ache from where her body had cushioned the fall.

"Thank you, Shirakawa Sensei."

Without rejecting Shirakawa Miwa's suggestion, Tsukishima Kyouko took a seat in the now-straightened chair and looked at Ito Yoshito.

"Ito, could you please help me pick up my shoes?"

After a brief period of calm, Ito Yoshito began to feel like his energetic blood had cooled down.

He bent down, picked up Tsukishima Kyouko's high heels, and squatted beside her, preparing to help her put them on.

"No need, I can do it myself."

Tsukishima Kyouko shot Ito Yoshito a slightly frustrated look as she snatched the heels from his hands.

'This little perv, Shirakawa Sensei is still here!'

"Alright, let's go."

Now wearing her shoes, Tsukishima Kyouko seemed to regain her usual icy demeanor and led the way out of the guidance room, with Ito Yoshito following behind her.

'I can't shake the feeling that Tsukishima Sensei and Ito have a pretty good relationship...'

Although Tsukishima Kyouko was very careful in her movements, the observant Shirakawa Miwa noticed the interactions between them.

Outside, the bright sunlight illuminated the dark curtains, which seemed to absorb the light, blocking it from penetrating the heavy darkness inside.

As Ito Yoshito, Tsukishima Kyouko, and Shirakawa Miwa entered the now dimly lit infirmary, the only source of light was the computer in front of Mizuki Hazuki, casting a faint yet glaring glow in the otherwise murky room.

"Mizuki Sensei, can't you open the curtains?"

"I'm used to it."

Shirakawa Miwa approached the window and drew back the tightly closed curtains, letting the sunlight stream in and dispelling the gloom within the room.

"That's not good for your eyes."

Mizuki Hazuki turned her gaze to the three visitors. Her once-attractive face was now shadowed by dark circles under her eyes, and her long hair was in disarray, giving her an air of fatigue—but not untidiness—just an alluring kind of dishevelment.

It was no wonder that the school's reputation of Mizuki Hazuki wasn't very good. Despite being a beauty, she always presented a haggard appearance due to her lack of self-care.

Add to that her disinclination to interact with people and her eccentric behaviors in the name of research, it's easy to see why rumors about her being odd circulated at school.

The last time Ito Yoshito saw Mizuki Hazuki, she was all dressed up, probably a rare sight.

"Yawn—"

Mizuki Hazuki lazily stretched and glanced at the trio with tired eyes.

"What brings you here?"

"Tsukishima Sensei fell earlier and is feeling a bit unwell, so we came to see you."

"I see… yawning—then follow me!"

After getting up and stretching, Mizuki Hazuki walked toward the bed in the back of the room.

"Clank clank."

After Tsukishima Kyouko followed her into the room, Mizuki Hazuki drew the privacy curtain around them.

"Tsukishima Sensei, sit there while I check your condition."

"Okay."

"Where do you feel uncomfortable?"

"My chest..."

"Then take it off—this will make it easier to examine."

Though Tsukishima Kyouko felt slightly shy, she complied with Mizuki Hazuki's instructions.

Mizuki Hazuki focused on examining Tsukishima Kyouko. Her fingers moved gently, carefully searching for any discomfort.

"Does this hurt?"

Mizuki Hazuki pressed down on Tsukishima Kyouko's chest, momentarily losing her composure as she squeezed a little too firmly.

"Wow! So big! How envious."

Tsukishima Kyouko felt a deep wave of embarrassment and yelped, "Ah! N-no, it doesn't hurt… Mizuki Sensei, please stop this inappropriate behavior!"

"Tsk, at your age..."

The examination did not go smoothly; a discussion appeared to spark a light argument, filled with topics that visibly energized Ito Yoshito.

Just as he was about to continue listening intently, Shirakawa Miwa's blushing face suddenly caught his attention.

"Ito-kun, let's wait outside for a bit!"

Gripping Ito Yoshito's wrist with her delicate hand, she firmly led him out of the room.

"Wait, Shirakawa Sensei, I'm feeling a bit unwell too!"

The door shut, cutting off their conversation.

"…"

Shirakawa Miwa's rosy cheeks curved into an alluring smile, exuding an unusual tenderness.

"Ito-kun, where do you feel unwell? If you don't mind, Sensei can take a look for you~"

"…"

"Alright, come in."

As she opened the door, the privacy curtain had already been drawn back, revealing Tsukishima Kyouko sitting on the bed with a flushed complexion, breathing slightly quicker than normal.

"She's fine, or rather, she's doing quite well. It's obvious she's been thoroughly indulged lately."

"Mizuki Sensei!"

Mizuki Hazuki yawned again.

"Alright, alright, if she's fine, you can go then. I need to take a nap too."

———— 

"Tsukishima Sensei, there isn't much time left for lunch; let's hurry to eat! Ito-kun, you too." 

"Well then, Tsukishima Sensei, Shirakawa Sensei, goodbye."

"Goodbye."

Watching the two girls leave together, Ito Yoshito prepared to return to the classroom to grab his lunch.

"Click."

The infirmary door swung open again, and a delicate white hand grasped Ito Yoshito's sleeve.

"Ito-kun—still remember the favor you agreed to help Sensei with last week? Well, now I really need you!"

A soft and charming voice spoke from behind him, a pair of soft hands encircling his waist. The gentle sensation against his back made Ito Yoshito stiffen for a moment but quickly relaxed thereafter.

"I understand. Sensei, whatever you need, I am at your service!"

———— 

Sunlight streamed through the curtain, casting a patchwork of light and shadow, outlining the two figures on the bed.

"Mizuki Sensei, bear with me; I'm going to apply more pressure now… how's this pressure?"

"Um… not bad, Ito-kun… a bit more pressure, please…"

The following sultry voice seemed to be enduring something, her tone somewhat whiny.

If anyone happened to walk into the infirmary at that moment, they would find this pair in—

A massage!

That's right; at that moment, the scene revealed—

Mizuki Hazuki lying on her stomach while Ito Yoshito sat at the edge of the bed, turned sideways as he gave her a shoulder massage, gently kneading and rubbing.

"Ito-kun, your technique is quite skilled~ Are you sure this is your first time massaging a girl?"

'What an acute observation!' Ito Yoshito thought to himself, silently praising Mizuki Hazuki's ability to read people. However, admitting the truth was out of the question.

"Of course! This is my first massage, and it's for you, Sensei."

Ito Yoshito focused on the beauty before him. Mizuki Hazuki's half-closed eyes displayed a lazy demeanor, and under his massage, she slightly furrowed her brows.

"Oh~ really?"

"Absolutely!"

"Then… why do I smell a hint of prostate fluid on Tsukishima Sensei…? My sense of smell is quite sharp, you know."

Like a lazy Persian cat, Mizuki Hazuki had somehow risen on her elbows, effortlessly twisting around to face him, her slightly squinted eyes enhanced by the subtle dark circles beneath them. Instead of appearing dreary, they added a touch of dangerously alluring charm, reminiscent of a poppy—dangerous yet enticing.

　　"!" 

"Sen- Sensei..." 

A bead of cold sweat trickled down Ito Yuushi's forehead, falling from his face just as he was about to say something, only to have a slender finger gently pressed against his lips.

"Don't panic, Sensei. Since Ito-kun has said so, it must be true. After all, you've never been with any other girls, right~?" 

Mizuki Hazuki leaned against Ito Yuushi, wiping away the sweat, her cherry-red lips letting out a soft sigh. "Isn't that right, Ito-kun?"

"…"

"Sensei, what do you want me to do…"

Mizuki Hazuki smiled slightly and sprawled back on the bed. 

"Ito-kun, may I ask you a question?"

"Go ahead."

"Do you think I possess the charm of a woman?"

Ito Yuushi was momentarily taken aback; that question required no contemplation. 

"Mizuki Sensei, you are indeed charming, whether it's your neat and sunny appearance or the current disheveled yet beautiful aura you exude. Each style has its allure, providing immense appeal to men… at least it does for me." 

"Pfft," Mizuki Hazuki chuckled, covering her mouth with her small hand. 

"Ito-kun, you really know how to win a girl's heart." 

"...I'm just speaking the truth."

"Mm-hmm—"

Mizuki Hazuki's smile dimmed slightly, as if reflecting on an unpleasant past, and she slowly continued, "Once, I had a boyfriend, and we were even engaged." Her voice dropped, "But in the end, I chose to part ways with him…"

After a pause of silence, she continued, "When he was pursuing me, he was polite, considerate, and charming. I was attracted to his poise and talent, and gradually opened my heart to accept his love."

"During our time together, he was very attentive, and I thought I found a lifelong partner…"

As she spoke, her memories came flooding back. 

"Until one day, I accidentally discovered some suggestive messages on his phone…"

Mizuki Hazuki's voice caught in her throat, her eyes betraying a profound sense of loss.

"...Did he cheat?" 

"Mm…"

"But it was hard to be surprised by a man as impressive as him having other women."

There was a brief pause in Mizuki Hazuki's words, as if reliving the shock of that moment. 

"At that time, I was saddened, but I still didn't want to believe it. So I secretly went through his phone…"

"Until I guessed the password to a hidden album and saw some photos that left me astounded…"

"I thought they might be pictures of other women's naked forms, but I never expected…"

"Wasn't it a woman?" Ito Yuushi's voice was laced with disbelief.

"He didn't truly love me. He only dated me to disguise his sexuality. He used his gentle and caring facade to mask the truth within." 

Mizuki Hazuki's voice gradually became softer. 

"At that moment, I felt deceived and betrayed; all my beautiful fantasies were shattered in an instant. I couldn't accept his lies, and we ultimately broke up."

Her expression became somber, as if her very spirit had been drained, making her seem fragile. 

"Being defeated by a woman alone would have been bearable, but being betrayed by a man in such a way made Mizuki Hazuki question her own allure. This sense of defeat was something she couldn't shake off.

"Ah—speaking about it feels a bit better. My parents don't understand why I broke up with him, and I have no friends to confide in."

"After quitting my previous job, I left my hometown and came to this school as a laid-back health instructor on my mentor's recommendation. In my free time, I assist my mentor with research." 

"Perhaps I got too engrossed in my studies… People often thought I was a reclusive oddball. Honestly, I feel quite lonely…" 

Mizuki Hazuki's voice held a tinge of melancholy. 

"…"

As Mizuki Hazuki fell silent, the last echoes of her words gradually faded, and the room returned to a calm stillness, disrupted only by the gentle sound of their breathing and the soft rustling of movement.

"Ito-kun, now that I've shared so much, I actually want to exchange secrets with you!" 

Mizuki Hazuki suddenly smiled, as though the heavy topic they had just discussed was no longer hers to bear. Only the glimmer of dampness lingered at the corners of her eyes…

She extended her finger, poking Ito Yuushi on the chest. 

"Now, we both know each other's secrets!"

Ito Yuushi was caught off guard.

"Secrets?"

"Exactly. I've learned about your secret with Tsukishima Sensei, and you now know my secret of being cheated on by a man."

"We both hold leverage over one another."

'It feels like something isn't right, but then again, maybe it is.' He couldn't shake the feeling that he had stumbled into a trap.

"Why tell me all this?"

"Do you believe in love at first sight?"

"Love at first sight?"

"From the moment I first laid eyes on your physique, I knew that someone with such a body must have an inner world bursting with unimaginable desire." 

"It's only natural that you would be drawn to someone like me, with my unremarkable figure and lack of feminine charm."

"So, Mizuki Sensei, have you developed feelings for me?"

"Rather than saying I'm attracted to you at first sight, I'd say I'm fascinated by the way you control such a remarkable physique."

"After all, a woman like me could spark your desire too. Hehe~"

"…"

He glanced at Mizuki Hazuki, who lay sideways on the bed, her perfectly arched eyebrows, slightly troubled demeanor, straight nose, and delicate face… 

The fitted white lab coat contrasted with her subtly alluring red camisole, accentuating her slim waist, the impressive curve of her hips, and the tantalizing space where her skirt met her sheer stockings…

Not to mention those plush thighs, slightly compressed together, and her elegant feet covered by the stockings.

'Mizuki Sensei, how unaware are you of your charm! Just a single setback made you completely doubt yourself... Though being cheated on by a man certainly does hurt a woman's pride.' 

"So, Ito-kun, let's have a chat in the health room whenever you're free. Who knows…" 

Mizuki Hazuki's rosy tongue playfully darted across her lips.

"Bang!"

As she watched the door close behind Ito Yuushi, his figure disappeared completely, and Mizuki Hazuki silently smiled. 

Indeed, she hadn't lied earlier; she had genuinely been cheated on by a man and lost confidence in her allure.

Yet, ever since she had been hurt, romantic feelings between men and women had become merely a spice in her academic endeavors. 

She had fallen for Ito Yuushi at first sight, drawn to his robust physique. 

There was romantic interest, yes, but…

There was another part she hadn't fully disclosed: the researcher's fascination with a lab rat…

On her clean writing desk, a bottle of transparent liquid rested in the corner.

Under the mottled sunlight, it gradually transformed into a pink potion, reflecting Mizuki Hazuki's enchanting yet perilous smile, reminiscent of a poppy flower.

Elofam's message:

Okay, I know you're looking for R18 scenes.

That's where it's headed.

The page where this novel was created blocks a lot of that.

So the author can't write it.

Therefore, I want to ask you: Do you want "special R18 chapters" written by me?

They are not "official" chapters.

I'm not a writer, nor do I have any talent, so it's possible you might see a bit of personality or setting change.

For one week, I will check the comments for this chapter.

If there is a minimum "yes," I will start posting them.

Although there will be few....

Also... I will make some appear in the previous 50 chapters.

(If the results says "yes" = the chapters will have "."

Something like "100.1")
