"What then?"

"Huh, what about what?"

Gu Jingxing's calloused fingertips stroked her cheek: "I delayed your homework, so what should I do?"

Song Ran raised his eyebrows and smiled: "Compensate me and give me a make-up lesson." ”

Gu Jingxing laughed in a low voice: "Okay, I'll make up for you." ”

Song Ran asked again, "Do you have a final exam for adult undergraduates?"

"Well, the troops are there. ”

"And how much did you score?"

Gu Jingxing raised his eyebrows and looked at her: "Which discipline are you asking?"

"Advanced Mathematics. ”

"One hundred. ”

Song Ran trembled and pointed at him: "You...... With such a high score in the exam, the subject only scored half of your score, and the disparity in strength is so big, the main responsibility lies with you, and you usually don't affect me in a way that affects me. ”

Gu Jingxing laughed in a low voice, stretched out his hand to rub her head, and the laughter was particularly doting: "Okay, good, the responsibility is on me, it's on me, I'll help you with your tuition, and you will be guilty, okay?"

Song Ran pinched his report card, his psychological imbalance was extreme, and he asked again: "How are you doing in other subjects?

"Tested. ”

"How many points?"

"Ninety-eight points, perfect score for atomic physics, perfect score for electromagnetism, full score for thermodynamic statistics......"

Song Ran covered his heart: "Okay, okay, don't say it, if you keep talking, I'm going to beat someone." ”

Gu Jingxing chuckled: "I'm more idle than you, I have time to study, you're too busy." ”

Song Ran nodded: "That's right, I'm just too busy." ”

That's a good excuse.

Gu Jingxing touched her head: "Okay, let's have dinner first, after eating, I'll teach you a lesson, if you master the method in high mathematics, you will be able to understand everything, it's not difficult." ”

Song Ran hung on him: "Then please ask Teacher Gu for more advice." ”

The two had dinner together, the sun was long, it was more than six o'clock, the sunset was still faintly sprinkled on the dining table through the balcony, Gu Jingxing's stewed fish head tofu soup was very delicious, and Song Ran couldn't help but drink two more bowls.

After eating, he couldn't hold his stomach and couldn't move.

Gu Jingxing washed the dishes and chopsticks and took the books: "Okay, the class has started." ”

Song Ran looked at him with a bitter face: "You don't need to be so conscientious, right? I just finished eating, can you let me rest for a while?"

Gu Jingxing pulled her and let her lean on him: "Well, you listen first, I'll talk about it, sort it out for you, let you know what it is, let you know what it is, sharpen the knife and don't chop wood, get the topic, you can't just bury your head and do it, you have to understand the deep meaning, so that next time the same question type, you will know everything." ”

Song Ran leaned on him and nodded frequently: "Well, it makes sense." ”

Gu Jingxing flipped through the book and began to lecture: "The more difficult thing in advanced mathematics is calculus, learning advanced mathematics, it is very important not to be limited by the ideas of middle school, some concepts in middle school are wrong......"

Song Ran leaned on him softly, listening to his deep voice, watching the sunset outside the window disappear into the horizon inch by inch, the earth gradually darkened, and her eyelids gradually drooped.

It's over, Song Ran, why did you become a scumbag who gets sleepy as soon as you listen to the class?

Probably the environment is too comfortable;

Probably Gu Jingxing's voice was too low and pleasant.

Song Ran leaned on his arm, and gradually, his eyes were completely closed, allowing me to close my eyes for a while.

Gu Jingxing talked for a long time, and when he turned his head, he saw that the girl was sleeping soundly, and she looked like a completely rotten wood that could not be carved.
