The_Hanged_Man1
i think this will be like authors POV where in that novel(spoiler ahead) ren Dover(MC) was a transmigrater who traveled into his own novel but turns out that all his memories of being the books author was fake because his actually a regressor who had his memories tampered with by his time remnant i think the same is happening here, his previous self created the false memories in himself that his from another world and that he played the game hi3 and his previous self also created the system
