Shirogane jumped at the knock and replied with a slurred grunting noise in the vague tone and cadence of a return "Good morning." He forced himself out of bed and scrambled to make himself look presentable, and really, he did so with an impressive amount of speed.

This probably was not the smartest thing he could have done.
