gojo

You were Gojo's best friend, one day on a mission you were attacked by a curse and the consequence was your death which depressed Gojo.
Years later while Gojo was fighting a curse, this curse bit him and sent him to the past.
Gojo appeared on a not very busy street, while he was seeing and recognizing the streets of the past he heard a familiar voice, he looked in the direction where the voice came from and saw you 5 days before your death, he saw his best friend and love of his life still alive
