Even Today, the Genius High School Programmer Cashes In on Day Trades, Completely Flustered by Beautiful Girls' Growing Affection.

“Hey, You’re Hitting Me”

“Nice—112,000 yen in the green.”

Three days after our group trip to the water park.

Classes were over. While I swapped out my indoor shoes at the shoe lockers, I checked today’s trading results on my phone.

The morning session on the Tokyo Stock Exchange had been quiet, but during lunch break the country’s largest automaker released stellar earnings. The afternoon session reacted positively; combined with the yen weakening further, manufacturing and export-related stocks surged across the board.

My program had executed flawlessly, locking in solid profits.

Investment balance now topped 4.5 million yen.

Just a little more to hit five million.

Our group of five still gathered desks together at lunch every day, eating side by side.

Conversation usually revolved around the pool outing, classes, random nonsense—nothing special, but somehow it felt… nice. Comfortable, everyday fun.

Most days it played out the same: Shingo and Ryuusenji trading banter like an old married couple, Yamano jumping in to fan the flames, and Sakuraba stepping in to mediate.

I mostly stayed quiet, listening.

Having spent so long eating alone, being part of this circle still felt oddly ticklish.

Ever since that day at the pool, though, I’d found myself hyper-aware of just how breathtakingly beautiful Sakuraba really was.

Glossy black hair that flowed like silk.

Large, expressive double-lidded eyes the color of burnt umber.

A refined nose and perfectly shaped lips.

And beneath the uniform… those large, pale, perfectly rounded breasts I’d glimpsed.

The dramatic curve of her waist.

I couldn’t stop noticing. Not after I’d seen.

“Truly the most beautiful girl in school.”

I let out a small, quiet sigh.

My phone buzzed in my hand.

A Lime message.

Hina: Meet at the west gate ticket barrier in front of the station right now.

Hina: If you don’t show, I’ll tell everyone how you were staring HARD at my boobs during air hockey lol

“‘Tell everyone lol’ my ass!”

I almost slammed the phone into the floor.

Is this how false accusations get born?

…Okay, maybe not entirely false.

How did Yamano even have my Lime ID?

Right—first day we met, she snatched my phone and forced an exchange.

“Meet at the west gate ticket barrier right now,” huh…

I had zero intention of going, but it seemed I had no real choice.

Grumbling, I headed that way anyway.

The station had two exits.

The east side, toward school, was lively with restaurants and foot traffic.

The west side—the one we called “behind the station”—was quiet, almost deserted.

Hardly any students came this way.

If Yamano picked a spot this empty… she had something planned, didn’t she?

I was fiddling with my phone in front of the west ticket barrier when—

“Yahhooooooo~!”

Twin-tails suddenly hooked around my arm.

Yamano.

“Hey—”

She looked up at me with mischievous eyes and deliberately pressed her chest against my forearm.

The overwhelming softness and pressure deformed the shape noticeably against my sleeve.

“Stop deliberately shoving those weapons into me.”

“Ehhh? Shouldn’t you be going ‘Hey, you’re hitting me!’ ‘You’re doing it on purpose~’ right about now? You’re no fun at all~”

“Not laughing. Don’t underestimate my iron will.”

She finally peeled herself off my arm.

That’s exactly why people call her a little devil.

“Say that all you want~ But you were totally staring at Hina’s chest the whole time we were playing air hockey~ Wanna touch them for real?”

“Seriously?”

“Yup! I’ll scream super loud though. Ooooh~ perveeert~!”

“Sorry sorry sorry I got carried away please forgive me—”

Total trap.

I’d tried to flip the power dynamic and make her back off—only to get instantly countered.

She wasn’t a little devil. She was a great demon.

“Well, it can’t be helped~ Boys are all like that anyway~”

Yamano grinned wickedly.

“Even at the pool the other day, Shingo-kun kept sneaking glances at Hina’s chest, and he was giving flirty looks to other girls too, so Aoi got super mad~ She was like, ‘He needs punishment! I’m gonna shove some pickled plums up his ass!’ and she was fuming~”

A brand-new urban legend was born right there.

Wait—Ryuusenji gets scary when she’s angry?

“I didn’t ask to have boobs this big, you know~ All the growth budget just went straight here instead of height~”

“Yeah, apologize to every flat-chested girl in the country.”

Maybe Ryuusenji’s reaction was extra intense because she’s on the smaller side herself?

“Enough about your chest. If that’s all, I’m going home.”

“Waaait, don’t be like thaaat~”

She turned her phone screen toward me.

“Do you know who this is?”

The photo showed a girl in uniform.

Hair cut straight and even, almost a classic bowl cut.

She wore maroon-framed glasses, and her face looked very youthful.
