Shikamaru and Sakura could go hide on the roof or go out too, if the home isn't private enough. But Shikamaru does bottle things up, someday that might bite him in the ass.

Well I see Ino jumping into Shikamaru's bedroom window trying to see if he and Sakura are totally making out. Instead it's just Shiakamaru napping or something equally boring to Ino. She'll keep trying, damnit!
