"Sakura already explained a little too much for that to make a difference, I think," Chouji informs him softly. "I'll wait, though." He regrets saying anything to make Shikamaru stop smiling, but he'd rather get that particular question over with as soon as possible.

Since it's Shikamaru, there probably isn't long to wait anyway. Chouji brightens at the question. "Of course! I'm already in a tree. I'll choose a tall one so you can find me more easily." He considers the surrounding area, then chooses a pine with branches well-spaced enough to avoid too much brushing up against uncomfortable needles, given he still isn't wearing a shirt.
