Regarding his doubts, Luo Fei expressed them in a very direct and clear way.

He picked up the pen and wrote a few words below Song Yifan's sentence in the exercise book.

"How so?"

Song Yifan seemed to prefer this way of communication without making a sound and only talking through writing, and she tacitly added three words under Luo Fei's words.

"You know. ”

Luo Fei didn't understand it at first.

This girl, speaking and writing and her style of acting are average, and she has never been able to see through.

Why does she think that Luo Fei should understand the reason behind this?

Luo Fei turned his gaze to her again.

The long jet-black hair that flowed down like a waterfall, the picturesque silhouette of the face, and the pair of crystal clear eyes under the long, dense eyelashes.

Song Yifan gently supported her right cheek with one hand, and placed the other hand on the table very casually, five slender and white fingers like daffodils gently knocked on the tabletop, the rhythm was as soothing as playing a piano, and her expression and posture were indescribably relaxed, as if Luo Fei around her did not exist at all.

This girl is really interesting.

Luo Fei secretly said in his heart, he didn't notice it himself, and a smile appeared on the corner of his mouth at this moment.

Is it because of Song Yifan's pleasing face, or is it because of the challenges she creates for Luo Fei all the time?

Luo Fei didn't know either.

His mind was on the matter at hand.

Perhaps it was the pressure and challenge given by this girl that made Luo Fei's thinking have to speed up.

The pace that had slowed down after the rebirth was brought up again.

Luo Fei, who has recovered to the previous level of seventy percent, thought about it for a while, and came up with the answer.

Song Yifan would definitely not investigate Luo Fei in private, this is not something she would deign to do because she is arrogant by nature.

She couldn't possibly get information from Kevin, who was not a man of the city, but he was very loyal to his friends.

So the only answer is -

Song Yifan got the clue from his math study book.

Because this is the only place where she can see the handwriting of Dolfe.

During this time, Luo Fei frequently appeared by Song Yifan's side, although the purpose was to improve his math scores.

But in this process, he inevitably had to expose his exercise book in front of Song Yifan, which provided Song Yifan with a window to observe Luo Fei.

Although there are not many places where Chinese characters are used in math problems, a few common Chinese characters are still used in the process of solving problems, and the negligent Luo Fei does not hide his elegant writing in this exercise book.

All this, of course, was seen by the sharp-eyed Song Yifan one by one.

Luo Fei didn't know when Song Yifan began to discover the similarities in these handwritings.

But since she discovered this, she was not in a hurry to expose Luo Fei, but as if nothing had happened, she watched Luo Fei come over and over again to ask questions as if nothing had happened, and she answered Luo Fei's questions again and again as if she had found nothing.

At the same time, taking the opportunity of Luo Fei's questions, he confirmed his handwriting again and again, and more and more consolidated the speculation in his heart.

When doing these things, Song Yifan did not show any flaws at all, her calm and indifferent successfully concealed Luo Fei's eyes, so that this man who has always been attentive did not notice that something was wrong, and still ran to Song Yifan like a fool.

As soon as he thought of his ugly appearance in front of Song Yifan, Luo Fei hated it so much.

This girl is really not to be underestimated.

However, although there is anger in the heart.

But when Luo Fei looked up at Song Yifan, he happened to meet her pair of shear-water eyes, and there seemed to be a whirlpool hidden in the clear water of the two bays, which made people involuntarily attracted to it.

Luo Fei suddenly felt a sense of amazement.

Although, Song Yifan's beauty has been recognized by everyone, Luo Fei has not seen her.

But before tonight, Luo Fei had never regarded Song Yifan's appearance as a very important thing.

Whether it is ghostwriting love letters for Kevin, or approaching her to improve mathematics, Luo Fei's actions to Song Yifan are with a very clear purpose.

And this purpose has nothing to do with her own attractions.

But Luo Fei has changed at this moment.

He suddenly found that the utilitarianism he had been using to measure the other party was gone, or rather, he couldn't think of the so-called reasons at the moment.

At this moment, there was only one voice in Luo Fei's heart.

Why is this girl so good-looking.

Her beautiful face, slightly raised small chin, and the faint smell in her clear eyes all made Luo Fei unable to take his eyes off it.

And the hidden arrogance in her eyes stimulated Luo Fei's competitiveness and desire to challenge even more.

Driven by this desire, Luo Fei picked up the pen and continued to write a few words.

"Like the letter I wrote?"

......

Although Song Yifan turned his face sideways, his eyes never left the boy beside him.

Her face was always cold, and her eyes were cold, as if she were looking at an object that had nothing to do with her.

But only Song Yifan herself knows that her behavior at this moment has surpassed the usual.

Because she has never paid more attention and cared about the actions of a person of the opposite sex than she does now.

If Luo Fei knew that he was the first boy to arouse Song Yifan's curiosity.

It is likely that his current state of mind will not be so calm, and his actions will not be so natural.

But even so, Luo Fei's behavior still made Song Yifan feel novel.

It's like the words he just wrote on paper.

It is not at all the gentle and polite manners of ordinary boys, but frank and straightforward, almost exposed, almost harassing.

But if Luo Fei was also like those boys, restrained and introspective in front of Song Yifan's coldness, then he would not have a chance to get close to Song Yifan at all.

Luo Fei's bold and direct behavior happened to point to the weakness of Song Yifan's character.

Although he repeatedly stepped on the edge of a very risky cliff, every time he stepped out, he stepped to the point.

This time was no exception.

When Song Yifan saw these words, he first felt a sense of being offended.

She couldn't help but glance at Luo Fei.

But this glance happened to meet Luo Fei's eyes looking at her.

Luo Fei's eyes this time were very different from the past, those eyes were not as deep and calm as the sea, but like the sea before the storm, and a storm and a tsunami were brewing inside.

This kind of look is extremely rare, so Song Yifan was attracted by what was in Luo Fei's eyes.

The two people are like magnets meeting magnets, their eyes locked by the gravitational pull in each other's eyes, and they can't be separated for a long time.

In the end, it was Song Yifan who took the first step to look away.

Only this time, there was an almost imperceptible smile on her lips.

Luo Fei keenly caught this smile that Song Yifan accidentally revealed.

Of course, he also caught a few words written by Song Yifan under Luo Fei.

The strokes of these words are dignified and dignified, but there is an extremely rare playfulness in the words.

"The word is good, the rest is average. ”
