” Er, sorry to bother.. But, uh.. Are ya any good at math..? “
Math was one of his worst subjects and one more nearly failing grade and he was gonna have to deal with a very unpleasant phone call from his father, hence why he was desperate enough to ask just about anybody for help at this point.
“Math–?? Are you kiddin’ me—??? You’d have better luck asking Kuro for help.”
Rin could barely pass his own classes, Shima must have been desperate to have asked the halfling for help on anything that involved learning. So not his style. “I could ask Yukio to give you a hand, but other than that, not much I can do for ya’.”
