During the Chunin entrance exam all ninjas had to fight against others

None of your teammates made it further except Neji, he won easily

During your fight, you and your opponent used a lot of chakra and energy but you still won but as soon as it was announced, your vision went black and you collapsed

The last thing you see is Neji jumping down the stands and rushing to your side and the first thing you see is him sitting next to your bed in the hospital room "How are you feeling?"
