Producer System: My Girlfriend is a Cellist

"So, this vertex is the climax part, right?"

"That's right. Now, you go 'perform' this problem." Lin Tian said with a smile.

Gan Yanyu immediately picked up the pen and dramatically drew a few musical notes on the draft paper.

Then suddenly stopped: "Wait, how do I calculate this climax part again?"

Lin Tian suppressed his laughter and pointed at the formula with the tip of his pen,

"Use this formula, just like you find the root of the chord on a score."

"....."

Gan Yanyu quickly calculated again, but still got it wrong.

The girl showed a sorrowful expression and let out a wail:

"I can't do it, Mr. Lin. My brain might be suited for playing the violin, not arithmetic..."

"Impossible."

Lin Tian gently patted Gan Yanyu's back, smiling,

"I've always recognized Mr. Gan's learning ability. There's nothing our Little Gan can't learn."

Gan Yanyu looked at Lin Tian with a guilty expression,

"Really...? You trust me that much?"

"Of course."

Lin Tian said sincerely.

Anyone can doubt, but never doubt Tongzi Ge!

— Of course,

Even without Tongzi Ge, when Gan Yanyu was studying acting before, she made a deep impression on Lin Tian.

She truly managed to fool him, who had master-level acting skills, into confusion.

Lin Tian ruffled Gan Yanyu's hair,

"Don't rush. Take it slow. When you play the violin, don't you start learning from the simplest scales?"

"But scales don't give me a headache."

"How about this."

Lin Tian thought for a moment and got up, "Let's get practical."

"..."

The two moved the 'battlefield' to the café.

Gan Yanyu's workbook was placed on the chair while Lin Tian sat at the piano.

Next, Lin Tian played a segment from "Miss Cat's Summer," including a simple melody.

"This is the X-axis."

Then Lin Tian played a high note segment,

"This is the Y-axis."

"Now, let's combine them."

"....."

A cheerful piano sound resonated.

Gradually, Gan Yanyu's eyes brightened,

"I think I'm getting the hang of it!"

Quickly, Gan Yanyu picked up the pen again.

Tore off the previous page full of scribbles written in two hours, and started fresh on a blank page, jotting down calculations.

Eventually, she got the correct answer.

Gan Yanyu jumped up excitedly, "I did it, Mr. Lin!"

"Lin Tian, you truly are the best teacher ever!"

Lin Tian watched her with a smile,

"It was your acuity. Actually, this problem for a student with a weak foundation like you is quite advanced. Solving it is already remarkable."

"No way! You're the best, Mr. Lin!"

Gan Yanyu said, as she suddenly pounced from behind, hugging Lin Tian's neck.

The soft touch pressed onto the juvenile's nape, the girl's chin resting on Lin Tian's head.

Lin Tian's head jerked up, almost thrown off balance, holding onto the piano, causing the keys to emit a discordant sound.

He turned his head and looked at Gan Yanyu, who rarely appeared so lively, his eyes gentle,

"So, how do you plan to repay your teacher?"

"Gift you a stuffed toy?"

"Why a stuffed toy?"

"Didn't you say, no girl has ever given you a stuffed toy?"

Gan Yanyu laughed and said,

"A teddy bear? A piglet? What do you want?"

"I want Little Gan's."

Lin Tian's eyes were clear,

"Even better if it's life-sized."

"....."

Gan Yanyu fell silent.

"Don't suddenly go quiet!!"

Lin Tian was flustered.

Having a nice conversation, and then suddenly this, doesn't make Lin Tian look like a creep?!

Gan Yanyu sure knows how to control the atmosphere.

"A toy like this might make you... a bit less lonely?" Gan Yanyu lowered her gaze, softly said.

....makes me seem more like a creep!

Gan Yanyu's pretty pure face lowered, with a conflicted and struggling look, as if the blond Lin Tian were forcing her into something unpleasant!

"After all, it's my fault... If I make you lonely, I'll feel sad too..."

Probably remembering Lin Tian's earlier playful behavior, Gan Yanyu said again softly.

"Then in that case... then no."

"Huh...?"

Gan Yanyu raised her head, Lin Tian said seriously:

"What do you take me for? Just a simple toy to settle me with?"

"Days without being able to marry Little Gan, nothing can fill my empty, lonely, cold heart!"

Lin Tian feigned frustration, lamented dramatically, clutching his chest.

"So... so sorry...."

Gan Yanyu hurriedly grabbed Lin Tian's hand from the piano, fingers stroked at his palm.

The next moment, Lin Tian pulled her down, seating her on the piano chair.

"If you want to make it up to me, then you should....."

"What....."

Gan Yanyu swallowed, staring blankly at Lin Tian with innocent eyes.

"Study well! Pass the college entrance exam!"

Lin Tian extended his index finger and tapped Gan Yanyu's forehead,

"Only then can we get closer to our dreams!"

The latter immediately held her forehead, letting out a wail.

The girl squatted on the ground, after a moment, finally raised her head.

Then she suddenly lunged into Lin Tian's arms,

"Dummy Lin Tian! Dummy Lin Tian!"

Gan Yanyu called out, scratching Lin Tian's belly with her small hands.

Lin Tian, laughing uncontrollably, was puzzled, utterly confused,

"Wh...What's wrong?"

"Did I say something wrong??"

"Was I too rough, then you should tap my forehead too..."
