"Do you understand this?" Friend P pointed to the formula.

I shook my head at the one that I couldn't read, which I couldn't understand.

"It's just a simple formula! This is the moment, this is the force! Friend P took a pen and pulled out a line and poked it hard.

I was about to cry: "I don't understand. ”

"Eh~ I'm convinced, you're so good at math, why don't you understand this."

A new page of paper was torn open again, and friend P frowned and flipped through it, and covered it back, almost crazy: "What don't you understand?" ”

"Hmm......" I stared at the formula for a long time: "You tell it again, and I'll understand it if you say it again." ”

"You...... This! Friend P almost didn't come up in one breath, the pen rattled in his hand, and slammed on the table.

Picked it up again and sighed: "Okay...... I'll tell you again. ”

I couldn't help but prick up my ears and pull my chair towards him, and then move again.

"Come here! I'm not going to eat you again......"

My brain twitched and I muttered, "Will ......"

Friend P: "......"

The atmosphere was a little weird and silent, and I looked up and bumped into him staring at me in a daze.

"Did I say something wrong?" I touched my face.

"Hmm...... Ahem. He put his hand into his lips and coughed twice, looking away.

"It does......" he whispered, turning his gaze to my book.

The book was opened in an uproar, and I don't know if my friend P's hands were shaking or what, and I didn't turn to the correct page number after turning it several times.

"Look at this ......," he pointed to me, pointing to the corner of the book.

I cheered up and listened attentively.

For a while......

I frowned and struggled out of the formula in the book, "I seem to know, you see me do it." ”

Ripping through his scratch paper, he flipped through the blank space and calculated according to the steps he had just described.

"Yes...... Is that so...... Get this first...... "I'm writing it pretty seriously.

"And then it went on......" I still frowned, and wrote line by line, why is this question so long.

finally wrote to the end of the paper, and a line of words came into view, neatly -

"The moon under the sea is the moon in the sky, and the person in front of you is the sweetheart."

My friend P watched me write down one stroke at a time, so the first moment he saw this sentence, he pulled the scratch paper out of my hand with a "swish".

"You're right." With a blank face, he stuffed the notebook roll and roll handle.

I argued: "I'm not done yet. ”

"Then you're doing the right thing." He was still expressionless, and stuffed the notebook to death: "You don't have to count to know that you are right." ”

Me: "......"

I couldn't help but stretch out my index finger and poke his expressionless face: "Are you...... Isn't it ......"

"Shy?" I asked, poking him in the face.

My friend P was expecting something I could say, but he poked and blushed.

He shook my hand away: "What are you doing?" Don't touch me. ”

"You're really shy." I came to a serious conclusion.

Why didn't I find my friend P so thin-skinned before?

"You're shy." He rubbed his face and found that he could not continue to speak, so he looked at the book and looked at the question.

After a long time, I remembered a sentence and asked me: "Have you finished reading the review questions?" ”

"Nope." I was bored flipping through my textbooks.

"Hiss~" He patted his brain: "I should have told you about the review questions first!" You can't pass without reading the review questions. ”

Me: "......"

"Ahhh Exams are coming up tomorrow! ”l0ns3v3
