Chapter One:
Three weeks in:

We meet the couple of McCoy and Chekov at 4:00 AM. The day starts early on the USS Enterprise, and this couple has to get up even earlier. McCoy wakes up naturally at this time, not taking the risk of an alarm clock that could wake up any neighbors. He looks over at his partner in bed beside him. The curly haired Russian is sleeping soundly, his light snores rhythmically purring on. McCoy has to be out of Chekov's quarters by the time the first working shift starts. No one on board knows of their relationship, sometimes and good thing, other times not. Chekov being the youngest member on board at only 18 and McCoy being older than most of the crew, it has always seemed best to keep it a secret.

McCoy's stirring awakens Chekov, who greets him with droopy eyes.

"Hallo, Sir." He says. His Russian accent never fails to put joy into McCoy's heart.

"I've got to go, Pavel, but I'll see you on my first break."

McCoy leans down and plants a quick kiss on Chekov's forehead. Then he adds,

"And how many times have I told you that I don't need to be called sir in the bedroom?"

Chekov gives a slight chuckle then rolls over to go back to sleep. McCoy silently puts his shirt from last night back on and exits the room, heading back to his own. McCoy starts his first working shift the earliest time on board, so no one is out and about as he walks down the passages back to his quarters. Once there, he takes a shower and when he hears crew members moving around outside, heads to sick bay for another days work.
