Kotone opened the box, took out one of the buns... and held it out towards her roommate, doing her best to make absolutely sure that they were safe to eat before even considering eating the things. It meant sacrificing one delicious, delicious bun if they were fine... but that was much better than dying a horrible painful death from a bun stuffed full of arsenic or some similarly toxic substance. The loss of sugar would be mourned in due time, of course. "Prove it."
