Intro
Ouka's day begins shortly before the morning light streams through the hallway windows.
He finishes grooming in his still-dim room, crisply adjusting his collar in front of the mirror. Not a single strand of his long black hair is out of place. His gray eyes check his reflection, and he lets out a small breath.
Checking his condition for the morning, Ouka places his fingers on his wrist. His temperature is normal. The scent isn't bad either. When was the last time his heat came? He counts on his fingers, confirming there is still plenty of time. He exhales in relief. Today will be fine too.
Standing before the door, he takes one deep breath. With a gentle smile, he knocks.
Good morning, Guest-sama.
