Despite being four high school students, thanks to the Shinomiya family's backing, Shin and the others smoothly secured a room.
And by sheer coincidence, it was the same room Shin, Hayasaka Ai, and Chika Fujiwara had used before—though it was obvious this was no accident. The Shinomiya family had undoubtedly arranged it.
At this point, the room might as well have been permanently reserved for Shin. Whenever he needed it in the future, he could bring any girl here without issue.
"So… what exactly are we supposed to do next?"
Kaguya Shinomiya sat on the sofa in the room, looking at Hayasaka with an inquisitive gaze.
The pink ambiance of the room gave her a strange feeling, but with her complete lack of knowledge in this area, she couldn't quite pinpoint what was off.
"Fujiwara-san will demonstrate for you. Lady Kaguya, all you need to do is observe and remember what they do."
Hayasaka maintained the perfect demeanor of a dutiful maid acting in her mistress's best interests. No one who saw her right now would ever suspect she was leading Shinomiya straight into a trap.
Truthfully, Hayasaka had considered demonstrating herself—but after what happened in the movie theater, she had completely exhausted her stamina and energy. There was no way she could go another round.
So, reluctantly, she passed the "demonstration" duty to Chika Fujiwara. Not that it mattered—judging by Fujiwara's behavior earlier, she had probably been tempted for a while now anyway.
Directly across from the sofa where Shinomiya sat was the room's large pink bed, where Fujiwara and Shin now perched.
To Shinomiya, it almost felt like watching a performance—except the stage was a bed, and the actors were Shin and Chika Fujiwara.
"Um… Shin-kun, maybe we should just… not do this?"
Sitting on the edge of the bed, Fujiwara turned to Shin, her voice tinged with awkwardness.
She had agreed to Hayasaka's proposal in the heat of the moment, but now that she was actually sitting beside Shin, under Shinomiya's unblinking stare, her nerves were fraying.
She was Kaguya Shinomiya's best friend! How could she do that kind of thing with Shinomiya's fiancé? And right in front of her, no less!
Sure, Shinomiya might be clueless about this sort of thing, but she wasn't stupid. If Fujiwara actually went through with it, Shinomiya would definitely stop them… right?
"Don't worry. Just leave it to me~"
Shin smiled at Fujiwara—her reaction was exactly what he had expected.
After all, in every sense, this was Fujiwara's first time. Shin knew to be gentle in moments like these.
(Of course, Hayasaka's experience had been rougher… but that was entirely due to Hayasaka's own preferences. Shin himself bore no responsibility for that.)
Staring at Shin's face so close to hers, Fujiwara finally gave up resisting. She closed her eyes and surrendered herself entirely to him.
Being watched by Shinomiya filled her with guilt—but paradoxically, that guilt only amplified the thrill.
Back at the inn, Hayasaka's words had awakened this twisted sense of excitement—the thrill of "betraying Kaguya." And now, that feeling had resurfaced.
Soon, Fujiwara felt her lips being captured. Her body trembled, then quickly melted into Shin's embrace.
The scent of him enveloped her completely.
"Th-That kind of thing…!"
Meanwhile, Kaguya Shinomiya, witnessing Shin and Fujiwara's lips locking together, was sent into a panic.
She might have been ignorant about many things, but even she knew what a kiss was.
Logically, she should have rushed over to stop them immediately—but with Hayasaka present, she instead turned to her maid, expecting her to intervene.
Yet Hayasaka made no move to stop them. Instead, she spoke to Shinomiya with utmost seriousness:
"Please observe carefully, Lady Kaguya. After marriage, you will also have to do this with Young Master Shin."
"Eh… EHHH?!"
That single sentence short-circuited Shinomiya's brain. She stared blankly at Hayasaka's dead-serious expression, then back at Shin and Fujiwara.
I'll have to do this after marriage… but Shin-kun and Fujiwara-san aren't married yet! They're already doing it!
"Young Master Shin and Fujiwara-san are merely demonstrating for your sake. This doesn't count as the real thing, so please rest assured."
Seeing Shinomiya's continued confusion, Hayasaka doubled down on her nonsense with a straight face.
"This is purely an educational activity."
Shinomiya's instincts screamed that something was off, but Hayasaka sounded so convincing, and Shin and Fujiwara showed no signs of stopping.
After a brief internal struggle, Shinomiya decided to suppress her doubts and keep watching.
Maybe I'm overthinking this? Maybe this really is just for educational purposes…
Given that her "special education" in this field had stalled at an elementary school level, there was no way she could tell whether this was a lesson or the real deal.
But when Shin and Fujiwara tumbled onto the bedsheets in each other's arms, she couldn't hold back anymore:
"Hayasaka! Are you sure this is just a lesson?! They're getting way too into it!!"
Shinomiya's face burned crimson. What Shin and Fujiwara were doing was far too intense for her innocent eyes.
For a young lady who hadn't even experienced her first kiss, their current actions were completely beyond her comprehension.
Sure, elementary-level "special education" might have mentioned the biological aspects of reproduction—but the actual process? She was utterly clueless.
This was her first time witnessing the full procedure so vividly.
"Don't worry. They're simply demonstrating what you will do in the future."
Hayasaka continued her unwavering act, her expression unchanging as she spoke.
"It only feels strange because you're thinking strange thoughts. Look—I can watch the entire thing without blushing at all."
Shinomiya blinked, then glanced at Hayasaka. True enough, the maid observed Shin and Fujiwara's actions without the slightest hint of embarrassment.
This only made Shinomiya flush harder—did that mean her own mind was dirtier than Hayasaka's?!
So, almost out of spite, Shinomiya stopped complaining. Instead, she widened her eyes and "studied" Shin and Fujiwara's "lesson" with exaggerated focus.
Of course, if Shinomiya knew what "post-nut clarity" was, she might have realized why Hayasaka remained so composed.
It was simple—after the movie theater, Hayasaka had already thoroughly exhausted her desires. Now, she was just peacefully along for the ride.
