My subject turned into a beautiful girl

An Yi almost immediately wanted to test the special effects of the MP3 and verify her guess.

But just as he was preparing to put his idea into practice...

[Your [computing ability greatly improved] effect, valid for six hours, has expired.]

[Friendly Reminder: Adequate rest is beneficial to physical and mental health]

An Yi stared at the suddenly popped-up screen, and before he could react, a strange drowsiness washed over him.

The feeling was like someone who had been exhausted and tormented all day, then went to an internet cafe for an all-nighter, and finally managed to get back to their bedroom, only to find their bed right in front of them... An Yi swore that he had never been this sleepy in his entire life!

In this state, it was impossible for him to test the newly acquired MP3 player, which was carefully selected by mathematics. He forced himself to stand up, not caring about tidying up, and after taking off his outer pants and slippers and turning off the light, he lay down on the mahjong mat.

The moment the back of An Yi's head touched the pillow, she could no longer resist the waves of drowsiness that washed over her, and was instantly swallowed up, drifting off to sleep.

His last thought before falling asleep was—

My "significantly improved memory" effect only lasts for a few minutes! I won't be able to use it all up, what a huge loss!

……

Something gently nudged An Yi twice.

"Um?"

An Yi suddenly looked up and opened his eyes, and the scene that came into view made him pause in surprise.

"Shouldn't I be sleeping in bed? Now...where am I? In the classroom?"

It was indeed a classroom, but not the one An Yi was familiar with; the furnishings were completely unfamiliar to him. He didn't recognize the teacher on the podium or the students below. The classroom was quiet, and the night sky outside the window was as black as ink, making it look like an evening self-study session.

Before An Yi could figure out what was going on, something nudged him from the side.

This time it was easy to tell: it was a hand that pushed him, and the force was very light.

He turned his head.

An Yi had learned many adjectives to describe a girl's beauty: bright eyes and white teeth, peerless beauty, stunningly beautiful, national beauty, and so beautiful that the moon hides its face and the flowers blush with shame... These were just random thoughts; if he were to write them down on paper, it would probably take him several minutes to finish.

But when he actually saw the girl beside him, none of the adjectives he had ever learned came to mind. The only words that naturally came to mind were those three simple, unadorned words—

She is so beautiful.

Mathematics, the girl with long silver hair and eyes as clear as the sky, is no longer just a character illustration; she is right here, right before his eyes.

It was his deskmate.

An Yi subconsciously held her breath, as if afraid that if she breathed too hard, she would wake up from her dream.

He had already recalled lying down in bed and falling asleep, and the only way he could possibly see mathematics was in his dreams...

But is this really just an ordinary dream?

Everything felt so real, so real that An Yi even doubted whether she was truly awake. Bright, soft light streamed from the overhead lights, cool air blew gently from the air conditioner, and the occasional sounds of pages turning and pens sliding filled the classroom…

It seems that he has always lived in this world. Mathematics is his childhood friend and deskmate. He just discovered that he was sleeping during evening self-study, so he gently nudged him to wake him up.

So what should I do next?

The thought flashed through An Yi's mind. He subconsciously opened his mouth, wanting to say something, but before he could utter a sound, he was interrupted by Mathematical Smile pouting and putting her index finger to her lips.

After gesturing for him to be quiet, she pointed to An Yi's desk drawer.

An Yi looked in the direction she pointed and saw a sky-blue MP3 player in the desk drawer. It had no brand or label and was about the size of a 2B eraser, with a faint shimmering light flowing over it.

He picked up the MP3 player, then looked at the math teacher and saw that the girl had already taken out a pair of wired headphones.

What followed was a natural progression.

During a quiet evening study session, the boy and girl sat close together, connected by a pair of ordinary wired headphones. A faint fragrance emanated from the girl, and an unknown melody played in the headphones.

Thus, the ordinary is no longer ordinary, and the mundane is no longer mundane. In a dreamlike state, the strings are plucked, and the melody is melodious and lingering.

……

"Um……"

An Yi opened her eyes.

The morning sunlight slanted in through the window, split into beams by the security bars, which shone brightly on the familiar ceiling.

But what was even more eye-catching was the light screen displayed in front of him—

[You listened to music with math for the first time in a long time]

Mathematics is delighted with this good start.

[Mathematics' favorability towards you +5]

Current Affection Level: 5/Normal

It wasn't a dream after all! Was it all really real?

A heart full of joy filled An Yi's heart, and she was even looking forward to the next time.

"Wait, what is this...?"

An Yi discovered that there was more content on the light screen, but he didn't seem to recognize it.

Under the control of thought, the screen scrolled to the top... displaying outdated messages—

You have used [an MP3 carefully selected by mathematics]

[The background music will excite you! You can choose any [inherent ability bonus] to temporarily double your boost!]

Currently, the only selectable [Inherent Ability Bonus] is [Mathematical Thinking Ability +1], which has been automatically selected.

Your [Mathematical Thinking Ability] has been boosted by +2! Duration: 1 hour

[Your [Mathematical Thinking Ability +2 Improvement] effect, valid for one hour, has expired.]

[Your [MP3 carefully selected by mathematics] battery is depleted and charging... Estimated full charge time: twelve hours]

[Current remaining charging time: 5 hours and 20 minutes...]

An Yi raised his wrist and glanced at the digital watch he hadn't taken off before going to bed last night. The time displayed was 6:40 a.m., while he remembered that he had gone to sleep around midnight...

"In that case, I must have used the MP3 in that 'dream,' and thus received a bonus effect. Since I was sleeping, this bonus expired after an hour, so I didn't actually experience it," An Yi thought.

Just from the description of the content on the screen, he could tell that the special effects corresponding to [MP3] were incredibly powerful!

The doubling mechanism has no limits.

Anyone who plays games regularly knows that this is a typical late-game god-tier attribute effect!

"However, as strong as it may be, only lasting for an hour at a time is far too short... And a 12-hour charge time is a bit outrageous! Is this MP3 player charged by static electricity?"

An Yi casually complained, then sprang to her feet in a somersault.

He slept exceptionally well last night, perhaps because he was in high spirits and full of energy.

After quickly packing her things and washing up, An Yi slung her backpack over her shoulder, picked up the six yuan breakfast money her mother had left on the counter the night before, and went out.

He was already looking forward to seeing how his older brother would react when he found out that he had completed the study plan in just one night!
