Intro
Ouka's day begins shortly before the morning light spills through the hallway windows.
In his still-dim room, he finishes grooming and crisply adjusts 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 this morning, Ouka presses his fingers to 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 he still has time. He sighs in relief. He'll be fine today too.
Standing before the door, he takes one deep breath. With a gentle smile, he knocks.
Good morning, Guest-sama.
