Striving to Become the Ideal Man in a World of Reversed Chastity

“Yaaawn...”

It was the middle of math class after lunch break; I was listening to the lesson while yawning. I was good at humanities subjects but really struggled with science subjects, so I needed to pay attention in class, yet I couldn’t stop yawning…

“Now, using the formula for this problem…”

(I’m so sleepy…)

I wasn’t tired at all when I was searching about love hotels during lunch break, but as soon as class had started, my drowsiness maxed out. Honestly, I felt like I could fall asleep at any moment.

Well, it couldn’t be helped. After all, classes right after lunch break were when you got the sleepiest.

…Actually, I was up almost all night. Those treasured videos and image files… sigh...

(But midterm exams are coming up soon, so I can’t afford to sleep…)

That’s right, the midterm exam period was about to start, so I couldn’t just keep slacking off. My academic ability was about average, so if I slept now, I might end up in hell.

If I got bad grades like failing marks, instead of my parents, I’d get lectured by Himeko, plus the bonus of being banned from club activities and part-time jobs. She always made me sit in seiza for hours while lecturing me.

Naturally, I hated Himeko’s long lectures… but more than that, now that all my “spicy videos and manga” had disappeared, I needed money to buy new treasures. And quickly too.

So if I got banned from my part-time job right now, I was definitely gonna die…

(I must absolutely prevent that…)

As a side note, Himeko was smart enough to always rank top in our grade. She always offered to help me study, but I refused every time. I didn’t want to see Himeko teaching me with that smug look on her face. I’d rather work hard on my own than see that smug face.

So I at least tried to pay attention to the minimum lessons needed to get scores good enough not to get scolded, but… it was impossible after pulling an all-nighter and eating lunch. I couldn’t concentrate at all… Oh no, I was about to fall asleep…

(…Hm?)

The schoolyard seemed a bit lively, so I looked out the window at the grounds to help stay awake.

Outside, the first-year students were having PE class. It looked like they were timing long-distance runs. As I absentmindedly watched the first-years running around the grounds, I saw a familiar female student running.

(Oh, it’s Hikasa. Man, she’s really fast.)

It was Hikasa, my junior from the club. Her leg power was overwhelmingly faster than the other girls. As expected of someone who trained her body every day in club activities.

(Wow… nice legs.)

I thought it was a bit sexy how Hikasa’s slender legs occasionally peeked out from her gym clothes. Thanks to that sexy sight, my eyes woke up a little. Yeah, being true to your sexual desires was a good thing, so I’d continue to faithfully live to my desires.

(Hmm, those are some healthy thighs!)

So as my drowsiness decreased, I decided to follow my instincts and keep watching Hikasa. It was clearly sexual harassment no matter how you looked at it, but I think it was allowed in this reversed world.

Looking at Hikasa more carefully, she had a great figure and was bright and charming, so she must be quite popular with the boys. Wait, did Hikasa have a boyfriend?

In my original world, I didn’t talk much about such things with Hikasa, so I was a bit curious. Maybe I’d chat about that next time I saw her.

While thinking about this and continuing to stare at Hikasa, I made eye contact with her after she finished her long-distance run. When Hikasa noticed me, she waved her hands energetically with a happy look. I also waved back slightly, careful not to let the teacher notice during class.

—Ding-dong, ding-dong…

“Haah… finally over…”

Math class finally ended. It was a miracle I’d managed to stay awake through the entire lecture. I should thank Hikasa’s slender, sexy legs for that.

“Fuah… but I’m still sleepy…”

My drowsiness faded a bit, but I was still tired nonetheless. “Aoi-kun, you look really sleepy.”

“Yeah, a little bit…”

Yuji, who sat nearby, spoke to me.

“Why don’t you go buy something to drink?”

“Hmm, maybe I should. I’ll go to the vending machine. Do you want something too? I can get it for you.”

“No, I’m fine. Have a safe trip.”

“Okay, got it.”

After finishing my conversation with Yuji, I stood up and started walking toward the vending machine in the hallway.

◇◇◇◇

At the vending machine.

“Ah, Senpai!”

“Hmm?”

As I was inserting a straw into my carton of coffee milk that I’d bought from the vending machine, someone suddenly called out to me. When I turned toward the voice, I saw Hikasa running toward me in her gym clothes, her feet pattering against the floor.

Come to think of it, this hallway with the vending machine was on the way from the grounds to the changing room.

“Oh, it’s Hikasa. Good work out there.”

“Thank you, Senpai. Good work to you too.”

Hikasa gave me a slight bow, but since she had just finished PE class, there was a bit of sweat on her forehead.

“You must be tired from PE. You didn’t need to run over here.”

“B-but, I wanted to talk to Senpai even if just for a moment, so…”

When I said that, Hikasa’s expression became a little dejected.

(Hmm, this version of Hikasa is like…)

The Hikasa in this world seemed to have stronger puppy-like qualities, or maybe a little brother (sister?) type of personality? I mean, she was always honest and serious in my original world, but here she seemed even more honest and obedient.

“But you were working hard in PE class. I was cheering for you in my heart.”

“Ah, th-thank you very much! Oh, that reminds me, Senpai. We made eye contact earlier, didn’t we?”

“Yeah, I was watching you run the whole time. You were super fast and looked really cool.”

“Really? Th-that’s good then, ehehe…”

When I honestly told her that, Hikasa’s expression changed from dejected to embarrassed, showing me a shy smile. It made me happy to see her genuinely pleased like this.

Seeing Hikasa being so pure and honest made me want to treat her well, and somehow I felt like I wanted to pamper her.

(Hmm, I see, this must be what they call maternal instinct… no, since I’m a man, it would be paternal instinct, right?)

I was thinking about such things with my eyes closed and arms crossed. Then, Hikasa looked at me with a puzzled expression.

“S-Senpai? Is something wrong?”

“Hm? Ah, no, it’s nothing.”

And so, having decided to become “the convenient guy”, I made up my mind about how to approach Hikasa. I think I’d follow my paternal instinct and pamper her in various ways. I guess it was what they called “big sister attribute” in my original world? Well, that was the kind of approach I’d take with Hikasa.

“Alright, since you’re here, I’ll treat my hardworking junior to a drink.”

“Eh, really? Thank you very much!”

“Yeah, what would you like…? yaaawn…”

“Um, let’s see… wow, Senpai, that’s quite a yawn!”

So I was planning to treat Hikasa to a drink, but I let out another big yawn at that moment.

“Yeah, I stayed up a bit late last night.”

“Oh, I see. Was there something interesting on TV?”

“No, that’s not it, ah…”

“Huh?”

I hesitated to say that I was looking for erotic videos and images until morning because it would be too embarrassing to tell a junior from the club…

(But from talking with Hikasa yesterday…)

From our conversation yesterday, Hikasa seemed to be the type who wanted to keep anything erotic hidden (the so-called closet pervert type).

So if I got embarrassed about these things, there was no way anything erotic would develop with Hikasa, right?

(Yeah, that’s right…)

Surely even if I kept pampering Hikasa, that alone wouldn’t lead to any erotic developments. After all, the closet pervert type would never try to create erotic situations on their own (this was just the opinion of a virgin high school boy).

So for Hikasa, just having a “big sister attribute” wasn’t enough… I needed to be an “erotic big sister type” to get Hikasa to make a move.

(Alright, let’s give it a try!)

And so, I revised my approach toward Hikasa.
