Sasuke sat on the same bed he's spent so much time in. It's like he always found a way to wind up back here. That thought angered him. It made him feel weak, that he couldn't go a single battle without passing out or getting injured, unlike Naruto who was still out there running around somewhere, despite putting in most of the effort in the battle

The jealousy rose as he thought about how Naruto was always the one to put all the effort into battles, making Sasuke appear powerless.
