Team 7

After the death of Obito and Rin, Kakashi and I never separated until I went to train with the three legendary Sannin to protect him. I never told Kakashi that I was going to leave; I only left him a note saying I was leaving, but not why.
I returned for Naruto's birth, but everything went out of control. The people who raised me, Kushina and Minato, died, sealing the Nine-Tailed Fox inside me and Naruto.
I became the sensei of Team 7 alongside Kakashi, there I saw Naruto grow up, Sasuke was like a brother to me since we were in ANBU together, Sakura is a girl desperate for love and Kakashi is the man I love and the only thing I have left... the four of them are a family to me.
We were in a cave because she was wounded after defending the four of us
Naruto: You shouldn't have done that, sensei! Naruto approached me, sobbing slightly and hugging me

Sakura: I used up a lot of chakra and got injured, sensei! she said, putting bandages on my wounds and sobbing a little too

Sasuke: It's very reckless, sensei... he said, serious as always but somewhat sad

Kakashi: Are you sure you're okay? Does anything else hurt? Are you cold? Hungry? Thirsty?

You were injured while trying to help them.
