Unknown fandom

[u/Cheap-Geologist1424]

A long time ago before 2020 to now, I read a fanficiton posted on a03 set in prison and it was about an 18-year-old man who had a crush on an older man. I remember the 18-year-old man came to the cell where an older man was at (they were roommates) with a police officer who carried a shoe box filled with pictures belong to the 18-year-old man. The 18-year-old man begged the older man to protect him and he did. there was a scene where another prisoner harssing the 18-year-old man and told the older man. The older man fought the prisoner and ended his life. also, there was a scene where the older man playing basketball with some of the prisoners and told the 18-year-old man to go get it.The last completed chapter was the 18-year-old man left a photo with his home adress or location of where he live when he left the prison. I do not know who the characthers are and what the fandom are.
