The New Year's Day holiday is not short, and after soaking in the library with Yu Huan for a while, Gu Jingshi had something to do with the company and was dragged away by Xia Jinnian.

Song Xinghe ran over to find Yu Huan's question, and he was still holding a physics textbook for the first year of high school in his hand.

It's going to rain red, and this guy is actually doing post-class questions!

Yu Huan glanced at him and said in confusion,

"Didn't you study abroad directly? Why did you start reviewing physics again? ”

Song Xinghe glared at her,

"Can't I be dying and struggling? If you are allowed to counterattack the adult one, I am not allowed to be a little self-motivated? ”

Yu Huan nodded,

"Yes, it's just that you're a little weird to be self-motivated."

This statement hit the nail on the head.

Song Xinghe propped up his chin dejectedly and said,

"I always think that Xia Mingwei has been a little weird lately, she used to give me lectures and accept my homework, but she doesn't care much about me lately, you say, does she think I'm too bad so she dislikes me!"

Yu Huan raised his eyes and glanced at him,

"Didn't you always complain about Xia Mingwei accepting your homework and doing the questions according to you? People don't care about you, don't they care about you? ”

Song Xinghe scratched his head,

"It should be like this, but in fact, I always feel that something is not right."

When he used to him, he thought she was annoying.

But now I don't care about him, and I don't know where it's empty.

Yu Huan picked up the thermos cup and drank water,

"What's even stranger, Lin Xia often disliked you before, and I haven't seen you so entangled."

"Lin Xia, can it be the same?"

Song Xinghe glared and complained ruthlessly,

"With her IQ, she still dislikes me? I still hate her! ”

Yu Huan buckled the lid of the thermos cup and lowered his eyebrows lightly,

"That's even weirder, don't you say that you still dislike Xia Mingwei?"

Song Xinghe was stunned for a moment when he was said, he was a little deflated,

"I don't dislike her very much."

As he spoke, he seemed to feel that something was wrong, and glared at Yu Huan and spoke,

"How do I feel like you're digging a hole for me?"

Yu Huan shrugged, and the carbon pen turned twice around his fingertips,

"Absolutely your delusion." Bunny Fly

Song Xinghe doubted,

"Really?"

Yu Huan poked his textbook,

"Which question won't?"

"This way!"

Song Xinghe immediately pointed,

"And the next page, no!"

"Master Huan, why don't you string me a string of knowledge points!"

Yu Huan looked at the crooked and miswritten formulas in his exercise book, and was slightly silent,

"I'll give you a suggestion."

"What advice?"

Song Xinghe's eyes lit up, she counterattacked so quickly, could it be that she had any martial arts secrets?

Yu Huan said,

"Change the CPU."

"Damn!"

Song Xinghe burst into foul language,

"You say I can't do it?!"

Yu Huan shook his head and sighed,

"You have a poor foundation, you haven't learned it at all, the direction of friction makes you draw it backwards."

"Is there one?"

Song Xinghe didn't believe it, Yu Huan took the tip of the pen and pointed it,

"It's the opposite direction, big brother, otherwise how would you balance!"

Song Xinghe drew a black dot with a carbon pen and an arrow in the opposite direction.

"There's gravity, it's perpendicular to the ground, not perpendicular to the plank."

Yu Huan corrected again, she felt that the current Song Xinghe had a fight with Gu Jingshi three years ago.

But soon, she felt that the gap between the two was still quite big.

Three years ago, Gu Jing didn't study, if he gave him a lecture seriously, he would draw inferences from one another, and learn quickly.

But Song Xinghe.... She gave him a question in the morning, and if she encountered the same type, she still wouldn't!

However, Song someone's honey confidently buttoned the pen cap,

"I'll just say I'm still very smart, and I understand after talking about it for a while, can you take your time, Master Huan, I'll invite you to dinner, let's continue in the afternoon?"
