Comments of chapter undefined of Attack on Titan: Reborn

TftC. Why Start so Early at Ymir Fritz Timeline? Tell me the Truth Author-san,You are Too Lazy to Do Research about Original Attack on Titan Plot&Canon and You don't wanna Remember all the Characters in AoT instead you want to fill the Fic with OCs so you made MC came in the Past. But do you know,Cause of your Intervention a lot of AoT Future's Plot&Canon Characters will Never be Born in the Future? Actions always have Consequences.
