In the private office of a teacher at Sobu High School—one responsible for teaching Japanese language and overseeing student life—
At the moment, a woman dressed in what looked like a size-too-small women's suit, covered by a white lab coat, took out a pack of Seven Star cigarettes from the breast pocket that was nearly bursting.
She tapped the filter end on the desk with the skill of a seasoned old smoker.
After slotting the cigarette in her mouth, she took out a 100-yen lighter, and with a crisp click, lit it.
She inhaled deeply, then exhaled a swirling ring of smoke.
"Haaah… What do I do now?"
The female teacher let out a conflicted sigh.
Class was starting soon, and the very first period happened to be her subject—with the very student who had her utterly at a loss.
She had no idea how to face him—ahhhhh!!!
As a woman in her late twenties, practically thirty, who had failed countless marriage interviews and was nagged daily by her parents to get married… she had, incredibly, kissed a student nearly ten years younger than her.
Beastly behavior!!!
"Hiratsuka Shizuka, you've lost your damn mind!!!"
Even though her demeanor was like that of a gruff old man and lacked any hint of femininity, she actually had a very pure heart.
Emotionally, she was closer to a 16- or 17-year-old girl—complete with a maiden's heart.
That day… it was all because of that goddess's warning—that everything was hopeless, that the world was ending—that she threw caution to the wind.
She gave away her almost-30-year-old virgin kiss to that little devil, Yazuki.
And not just a kiss—she used her tongue to pry open his lips. Thinking about it now, her heart thudded like a little deer about to burst out of her chest.
"Calm down, calm down, CALM DOWN, Hiratsuka Shizuka!"
She had looked so cool doing it that she'd totally disoriented that brat.
She couldn't act all shy and awkward when they met again—he'd definitely mock her and use it to launch some kind of payback.
She had to maintain authority. Authority over that brat.
No cracks, no blushing.
"Ugh—!"
A small yelp escaped as she burned herself with her cigarette. Another one down. The ashtray beside her already held seven or eight butts. The office reeked of smoke.
Maybe she should try that youth-enhancing state the goddess gave her. Show up in front of that brat looking all 16–17 years old.
Hmph, her younger self wasn't a bit worse than the school's #1 beauty, Yukinoshita Yukino.
No—better. Yukino had that flaw—her chest.
If that brat saw her like that, maybe he'd be enchanted… or maybe not. She wasn't sure. Yazuki was way too deep into anime to say for certain.
Knock knock.
Someone knocked on the door.
"Who is it?"
"Me."
Just one word, flat and unmistakable.
Hiratsuka's lips parted as she was about to light another cigarette, and the filter dropped from her mouth in shock.
What the hell? She checked the time. Damn it, the brat was actually early today—and had come straight to her office?
Was this for revenge?
"Wait—"
Swish. The door opened and he stepped right in.
"How many of those have you smoked?"
The one who entered was instantly hit by the strong smell of tobacco and frowned.
"Can't you cut back a bit?"
She smoked harder than a man. Was she trying to get lung cancer early?
"Adult business. No need for brats like you to nag me."
Hiratsuka waved dismissively, brows furrowed in irritation, picked up the fallen cigarette and lit it again.
Her whole attitude seemed like usual, as if nothing had happened the day before. Like that kiss never happened. No big deal.
Was it really just some throwaway moment to her?
"What do you want?"
Still playing the grumpy, annoyed teacher. But deep down, Hiratsuka's heart was about to leap out of her chest.
And then she saw Yazuki's slight smirk, her instincts screamed: something bad was coming. That brat was here for revenge.
What would he do?
"Sensei, give me back my first kiss."
At that moment, Yazuki gave her a look like a scorned lover, eyes full of wounded grievance.
"Uh—!"
He jumped straight to the point, catching her off guard. Hiratsuka broke into a cold sweat.
"First what? Don't be ridiculous. Just think of it as a European-style greeting kiss, would you? Don't make such a fuss."
She tried to keep her cool.
"Oh? A greeting kiss? Does that usually involve sticking your tongue into the other person's mouth?"
He shot back with a soul-piercing question, and Hiratsuka—who always prided herself on composure—wavered.
Her eyes darted, avoiding direct eye contact.
"Uh, well, that's… you know…"
She couldn't answer. This brat was definitely trying to make her squirm.
Damn it—maybe if she got mad and kicked him out, that would work. Just as she was about to do just that, Yazuki handed her his phone.
"What the—"
On the screen played a security cam clip showing a mature woman doing unspeakable things to a clearly underage boy.
That—that was HER. That desperate moment of hers!
Right then, Hiratsuka panicked for real.
"W-Why are you showing me this? Are you trying to blackmail me?"
She still sounded tough, but her voice trembled, her tone unsure, and cold sweat dripped down her face.
"What do you think, Sensei? If this video got out… what do you suppose would happen? I bet you'd make national TV."
At this point, Yazuki dropped the wounded-puppy act and gave her a full-on villain smirk—the kind of expression straight out of a hentai doujinshi where the male student uses blackmail to do unspeakable things to his female teacher.
Hiratsuka swallowed hard.
In her mind, she saw reporters crowding around her, asking why she did it.
Was she lonely? A frustrated pervert?
She was the school's life guidance counselor—supposed to be a moral example. What would the other teachers and students think? Her parents? Her friends?
"Uuugh…"
A mental image of total ruin flashed through her head.
Hiratsuka broke down, her tough façade shattered. She turned into a pitiful, helpless creature with teary eyes.
Yazuki lifted her chin gently and ran his fingers across her lips. Under that dangerous, playful gaze of his, her eyes welled up even more.
There was something in his expression—not just mischief, but also a strange coldness.
A slight change had taken root in Yazuki… something even he didn't notice himself.
"So, Sensei," he said softly, "what do you think we should do? I imagine… if I made some slightly unreasonable demands, you wouldn't be able to say no… right?"
