Chouji was too concerned for Hinata to be embarrassed by having her lean on his shoulder. She was a fellow Konoha ninja, a friend moreover, and she needed to rest. Obviously that was the most important thing, and Nala seconded that feeling, intensifying it. "You're welcome, Hinata," he answered contentedly, glad to be of some use.

Chouji reached out with a little of his own new power, seeing if there was anything more he could do. He let out a yawn of his own as he tried to ease Hinata's exhaustion somewhat.
