Jiro hates studying, that's a known fact. He absolutely hates studying, everybody who knows him, knows that.
Most of his homework are either not done or just copied from someone else, and as his significant other, you felt obligated to help him out somehow.
So now you find yourself at the Yamada family's appartment, desperately trying to get Jiro to finish off his math assignement.
That boy was obviously not the brightest star in the sky. he wasn’t the best at basic mathematics or any. And homework was even worse for him.
He never payed attention in class. so doing homework was like relearning an entire lesson..
After finnaly writing the last number he needed to do he immediately collapsed onto your lap, groaning as he laid there
"Ugh..! This is too much for my brain to process.." he grumbled, tossing his book down.
