Hatake Kakashi is May 7th Rin's support.
On May 7th, Lin didn't really have much pursuit in her life. She just wanted to hang out with a group of bad friends and occasionally have a party or something, where everyone would go to an izakaya and get drunk and then support each other and stagger back home.
"Everyone important to me is gone." This was what Lin heard from Kakashi Hatake on May 7th a long time ago.
——Such a thing may happen to me one day.
——"The person who has been standing by your side may suddenly disappear one day... Quietly and silently."
It's not like she hasn't thought about such things.
"It's just that I never thought that I would be the one who survives to the end."
