Lin Bai covered the back of his head, looking aggrieved, "Don't hit the head, what if you beat me stupid!" ”

Su Nian took the math book on the table, opened the page of trigonometric functions, and turned back a few pages in a row, except for the words on the book itself, there was not a single new word written on it.

The whole book is new, as if I haven't even opened it!

No wonder you can't do such a simple question!

Su Nian was about to leave, but now he had to sit down again, "Read the book first, start over, read it in ten minutes, and then do the question!" ”

"Ten minutes is too short," Lin Bai haggled, "at least twenty minutes, maybe... It's not enough. ”

Su Nian raised his hand, put it down again in Lin Bai's defensive gaze, and said sharply: "Hurry up and watch, don't waste a minute!" ”

She had planned to go back to her bedroom tonight, but now it seemed that she would have to go upstairs to sleep.

Lin Bai looked at the book, and suddenly looked at her after a while, "Sister, you can sleep here for a while, the master bedroom is for you, and I will live in the second bedroom!" ”

Su Nian: "I have a place to sleep, don't worry about it, hurry up and read a book!" ”

Lin Bai thought she was going back to school, "Your school is a bit far away, it's a big night, it's not safe for you to go back!" ”

Su Nian pointed upstairs, "I rented a house upstairs, and I'll go to sleep after you finish your homework." Lin Xiaobai, I warn you, from now on, don't speak, otherwise don't blame me for being rude! ”

Lin Bai stretched out an index finger, "Say the last sentence, what should I do if I have a problem?" ”

"If you have a question, just ask, don't say anything else, read the book!"

The phone vibrates, it's Yi Rin.

Su Nian moved to the side and sent a message to Yi Rin to chat.

She was playing with her mobile phone, but she had to study, Lin Bai was aggrieved, looking at a bunch of messy mathematical symbols such as sin and cos, her head hurt a little!

It took half an hour to read the book, and another half an hour to write homework, during which Su Nian didn't ask a single question.

Lin Bai has done it all, and it's already past twelve o'clock.

Su Nian checked his homework, all right!

A smile appeared at the corner of her mouth, "It's pretty much the same, go to bed early!" ”

She hadn't been to the house for nearly a month, and the table was dusty, and the bedroom was dusty.

Su Nian didn't often sleep here, so the quilt was put in the cabinet, she changed the sheets, hugged a quilt out, and after washing, she slept like this.

As for cleaning the room, let's talk about it tomorrow, she's not a particular person anyway.

Su Nian often stayed in the library until the middle of the night last semester before returning to the dormitory, and sometimes when she went back, Song Ziyu and the three of them had already slept.

They are used to Su Nian's late return, but they are not used to her not returning at night without saying hello!!

Early in the morning, Liu Yiran was woken up by the alarm clock, she sat up in a daze, rubbed her eyes and found that the quilt on the opposite side was neatly folded, and Su Nian didn't come back for one night.

She didn't consider the possibility of Su Nian getting up early to go out at all, because if there were no special circumstances, Su Nian would get up at seven o'clock in the morning, and she wouldn't get up a minute earlier.

Zhao Zixin also woke up, Liu Yiran saw that she moved, and hurriedly called her, "Xinxin, the great god didn't come back last night!" ”

Zhao Zixin's hair came out of the quilt in a mess, and she glanced at Su Nian, "Did she go home with something?" ”

Liu Yiran: "She usually tells us when she doesn't come back, ah!" Nothing will happen to her, right? I've seen the news before that college students were abducted on their way back to their dorm late at night......"

"Don't think about it, no," Zhao Zixin took out his mobile phone and sent a message to Su Nian: Great God, you didn't come back yesterday, is there something wrong?
