my theory similar to beware of the villainess and few kther logic id that the "system" is simialr to manmade itemsd where it was created a sd by product of authors power to creat a story (the theory that each story creates a real world elsewhere) and each time reader opensd the story a new dimension of the story is created and so the tranmigrated soul was a person of og world origin but loops out gainsd awareness somewhere along the way and comes back and system glitches
If the system wants their command (the words, the emotions) be strictly followed, what is even the purpose of transmigrating a soul from another world? Just make a character like all the other characters there?
