a self insert fic where a group of orphan children who see eren as a father figure get sent into an alternate time of aot with a titan form, where eren has a harem consisting of mikasa, historia, Annie, sasha, Petra, hanji, Frieda reiss, pieck and Lara tyburr the little sister of willy tyburr but there all killed by in the last battle with Marley, so eren goes back in time but messes up and does the original story, but just before he dies he sends a message back to his younger self telling him not to do what he did, but he dies before he can complete the message after he dies he meets the kids and comes see them as his children. also in this alternate timeline there are two other titans which i saw online and want to use that i won't reveal yet
