"I don't know how to do this one. And this, and this…" Opening the practice book, Zhao Yanzi circled with the ball-point pen.
"Urm, let me take a look…" Hao Ren forced himself to look through the problems.
"This is only Math. And I still have Physics, Chemistry, Biology, Geology…" One by one, like in a magic show, Zhao Yanzi pulled out many practice books from that little drawer.
Hao Ren was dizzy with exhaustion, and he could only solve a few of the problems. Meanwhile, Zhao Yanzi slouched in the chair with her arms crossed over her chest, looking at Hao Ren with a gloating smile.
"Damn! How come the science courses in middle school have gotten so difficult…" Hao Ren cursed silently. However, since he couldn't humiliate himself in front of Zhao Yanzi, he had to rack his brain on the problems.
