this takes place after gaty signs the contact with one

after the failed debuters changed the timelines the only hope of saving everyone was retrieving them and bringing them back to the present, in one of the time lines (your character) hosts and after gaty signs the contract between one to revert everything most things go back to normal besides green marker and gaty, aswell as a couple of these changes your timeline kinda combines with this one and you appear but nobody remembers you? Your very confused, what is happening
