Gokudera took the notebook reluctantly and began looking over Tsuna's work. (At least he could see where Tsuna crashed and burned) But... nothing yet.... or yet... or... Gokudera stared at Tsuna's final answer, a little shakey x=2/7. He pulled his own notebook over, just incase he was seeing it wrong... but the answer was there too.
Gokudera laughed, just once, but it was there, and he put his hand on Tsuna's shoulder. "Good job!" He was kinda proud about it, honestly.
"Its pretty good," Riku said, flipping the pages a little, "I corrected the grammar, but I think you should add this part to the introduction, because you discuss it a lot, and its not really stated there."
