Number 2. This time ANBU Kakashi. :)

"Rin?" he asked as he stepped into the apartment they'd shared for some time now. "You home?" this was the first time they'd have to say goodbye before an ANBU mission. He really hoped she was home; it'd brighten his day considerably just seeing her before he went.
He heard noises from their bedroom, and went there. Rin was busy putting on some clothes; obviously, she'd slept in as she was having night shifts as of lately, at the hospital. "Time already?" she asked, yawning. "Already?" a grin spread beneath Kakashi's mask, tainted his eye with a certain glint. "It's one pm, Rin."
"Already?" she yawned again as she tied her small apron. "Yeah." Kakashi confirmed, stepping in close, pulling down his mask and pulling her in for a kiss. Smiling against his lips, Rin put her arms around his neck, holding on for much longer than was strictly necessary. When they broke apart, she looked into his mismatched eyes; the Sharingan she'd transplanted into his left eye socket spinning slightly. "Mm. Take care. I'll miss you... Taichou." she smiled. It'd become another of her petnames for him.
"And I'll miss you too, my dear Medic."
