an update, because having this unfinished makes me feel lame.
Sakura can drag Kakashi's stupid ass down to the hospital whenever she wants now, because it is her right as his unspoken girlfriend. He now has the occasionally annual check up. Tsunade is suspicious at the change. (She tells Sakura that she's happy for her; Sakura's cheeks turn pink as Tsunade winks.)
Right now Kakashi is sitting shirtless on her exam table. She pokes him in the stomach and he winces: he's ticklish there.
"Open up," Sakura says, scowling. He mutely shakes his head.
"Stubborn man," she hisses. Kakashi's mask is still on, but he appears delighted with this description.
