"Okay everybody know what we're doing?" Hyun-woo, the class president of the homeroom, asks his class

"No..." People mutter

"Come on we have to do this for Lee-seong sang nim and Cho-seong sang nim."

"One more time everyone!" Ha-eun shouts 

"What is the equation we're supposed to graph and see if he can figure it out?"

"Okay the equation is (x2+y2-1)3-x2y3=0."

"And this actually works?"

"Do you need me to type it in for you, Hye-jin?"

"Yes."

"Okay... and there."

"Omo, it actually works."

"Here, I'll put the equation up on the board for everyone..." Hyun-woo says writing the equation under the "start of class problem" section of the board

"Teacher's coming!" The guard boy shouts as everybody gets into their seat and pretend to look like they're solving the equation

"Good morning class." Kyuhyun says as he walks into the classroom

"Good Morning, teacher," Hyun-woo says and starts the morning routine "Stand up! Attention! Bow,"

"Good Morning." The class mutters in unison

"Sit!"

"Okay, so today in math... what do we have here?"

"An equation for you, Cho-seong sang nim." Ha-eun

"This should be easy, since you've already set it to zero for me."

"No you can't solve this one, you have to graph it!" Hye-jin says

"Then maybe my class should leave more through instructions, so what would you like me to do with this equation?"

"Find the mid-point of this shape." Do-hyun suggests, to which everyone agrees

"So the midpoint of this shape, so it's not a line, and it's not a quadratic parabola.... so what could it be?"

"It's something som
