JJK fic recommendations please.

Hello,

I am looking for fic recommendations in the Jujutsu Kaisen fandom. I am new to the fandom and I would love some mentor/parental themed fics. It can be any of the characters and I don't mind any ships too. I just want the main focus of the fic to be the parental/mentor relationship between Character A and Character B.

I would appreciate any recommendations you have.
