100 ways to trick a boy into going to sleep

Chapter 509 Slowly, Slowly

However, the bath towel didn't cling to Cheng Shiqiu's body as she had expected.

"what happened?"

She simply stopped looking; out of sight, out of mind.

"I have a question I can't answer, could you teach me?"

Enjoy yourself: ? ? ?

Cheng Shiqiu's grades are not bad. Although he often performs outside, he has not neglected his academic studies at all. In the past, the two of them never talked about studying when they were together... Today, has the sun risen in the west?

However, since it was her boyfriend's request, she didn't refuse: "Which subject?" "Mathematics."

She might be better at humanities-related questions; while she's fine with math, she's not exceptionally good at it.

But since he asked, she can take a look first.

Cheng Shiqiu took out a test paper from the bedside table. The example problem marked with a red pen was a common one in high school mathematics: finding the equation of a curve, finding the monotonic interval, and comparing the size of the formula in the third sub-question.

At first glance, it seems quite complicated.

Actually, it's not that difficult to do, it just requires some scrap paper.

"You don't understand the third sub-question?"

"No, I don't know how to do it either." As soon as Cheng Shiqiu opened his mouth, Jin Huan knew he was talking nonsense.

"Draw the picture on the draft paper first."

She usually draws diagrams first when solving problems, as it makes them clearer. Cheng Shiqiu suddenly adjusted her posture and even put on a pair of gold-rimmed glasses.

For some reason... it just felt different.

Jin Huan gently pinched the corner of the blanket, trying her best to keep her eyes from wandering.

"There's no draft paper." He suddenly turned off the lights in the room, leaving only the dim light of the bedside lamp.

On the young boy's body, every bulging muscle exudes a youthful, robust strength.

His voice also became low and gentle in an instant.

The phone was pointed directly at him.

From this perspective, Jin Huan, sitting on the other side of the screen, always felt as if she were looking down at him from an unspeakable angle.

"Can I draw here?"

His fingertips lightly touched his obliques. Jin Huan subconsciously pursed her lips; she didn't want to admit it, but she seemed to be a little attracted to a handsome, young high school boy…

However, he answered honestly, "Yes."

"Then Huanhuan, can you check if my drawing is correct?"

"Okay." She sat up a little straighter, her eyes fixed on the phone screen.

Cheng Shiqiu started drawing from the x-axis and y-axis.

Jin Huan's drawing habit is usually to retain the first quadrant, but Cheng Shiqiu draws it perfectly, with all four quadrants appearing equally.

He draws very slowly.

Her eyes unconsciously followed his finger.

Cheng Shiqiu drew the y-axis short, just hitting the edge.

She felt somewhat regretful.

The problem provides three coordinates: a(-4, 6), b(4, 6), and c(0, -9).

"Huanhuan thinks point A should fall here, right?"

Cheng Shiqiu's voice was a little hoarse, and he looked at her with slightly dazed eyes.

In the second quadrant, the small point is in a very upright position, so the position of b is in the first quadrant.

Points a and b are exactly symmetrical.

"Yes, you pressed too lightly. Press it a little, it'll turn red." She just went along with what he said, a little agitated.

But he actually did it.

Point A has spread out a lot, increasing the three-dimensional effect, and as she wished, it has turned into a dark red.

"Qiuqiu, I want to see the center position."

"it is good."

The boy raised his phone slightly, his fingertips tracing the Y-axis downwards. "Huanhuan, C is at -9, what if we can't draw it?" His voice trembled slightly.

"Come down a bit, yes, that's it, sweetie, write it down, just like that, sweetie."
