... the following text ...
Kushida Kikyo has the talent to become Bichi.
Whether he lifted his hair and kissed him or undressed himself on the bed, he did it flawlessly and completely entered the role of Bichi. However, I was very disappointed. Ye Shenyue never rejected the girl, so yes He said, Kushida, you can come even more violently!
I looked at the time and it was only 21 pm, so Ye Shenyue just held the single cover and hid in bed with Kushida to read ... a book.
Although Kushida Campanulaceae can't be seen on the surface, it is actually an invisible school bully. Her grades are not top-notch, but they are also top-grade. Now, in such evening time, she is preparing for her homework.
Opening the math textbook, she is looking at the inverse function.
"Don't do it ... trouble."
Kushida didn't return her head, but she slapped Ye Shenyue on her shoulder with her hand, but the one below couldn't. She had to move her body, but the slight movement felt more intense.
She felt.
So her tone is quite bad.
But this is not good. The high probability is that it is difficult to read books.
What are the properties of inverse functions?
She happened to see this.
Supporting the body with one hand, Ye Shenyue asked herself not to suppress her, but turned over the pages of the book, "What do you want to see from here, what is the nature of the inverse function? ①The image of the inverse function is about a straight line y = x symmetry; ② save the monotonicity and odd function of the original function ... Then set the domain of y = f (x) to A, the range of value to C, a belongs to A, b belongs to C, ... "
"That's ..." Kushida was angry, but now it sounds. Focus on the pages of the book.
"And the example you just did, in fact, does not follow the textbook method, direct derivation is faster ... f (x) derivation ..."
The night Yuekou Ruoxuanhe's blind breaking ... No, explaining, but the real thing is diverting Kushida's attention and letting him release it again in her body.
The sheets have to be changed again.
Ye Shenyue panted on her body, but Kushida turned around, "Aya Koji, your grades are actually good?"
"Hori Kita helped me prepare and prepare for this part."
Ye Shenyue honestly lied, and now Kushida just suspected that he had helped Horibei a lot in private, but did not know his academic qualifications, so Ye Shenyue also bluntly asked him to bet on the subject. Horibei classmate memorize the pot again.
"cut."
Kushida immediately turned her head back, even though she was friendly to Hori Kita on the surface, but in private she hated her very much.
If Hori Kita immediately became a topic terminator when Kushida appeared, as long as Hori Kita's name is mentioned in front of Kushida who is good at communicative speaking, Kushida will quickly dissipate interest.
Like the yin and yang of a mountain, there is always repulsion.
"What do you think about Sudo?"
Ye Shenyue has nothing else, so relax and listen to Kushida's true emotions. "Is he helping him for classmates, friendship or other things?"
