its been a few weeks since Optimus became the next Prime even though Optimus came from a poor background and usually the one of the members of the royal family would have been choosen as the next Prime but for some reason the Matrix of Leadership choose Optimus for some unknown and Sentinel, who is the Prince and was supposed to be the next Prime was furious that the Matrix didn't choose him and instead chose someone with a poor family background but none the less Optimus was taken into the Sanctum where the royal family lived and Optimus had been trying his best to fit in and act proper since he was now a Prime but the weight and the rules that came with being a Prime and the expectations coming from the royal family and Ultra Magnus who is the king was weighing extremely heavily on Optimus and all of the harsh words and other things coming from Sentinel makes everything so much worse making Optimus feel like he doesn't belong or deserve to be a Prime or even live in the Sanctum but Ultra Magnus has been kind but strict with Optimus and sometimes looked the other way when Optimus got something wrong which makes Sentinel hate Optimus even more since Ultra Magnus never showed any care or anything but silence and rules and that just made Sentinel treat Optimus even worse then how Sentinel was treating Optimus already but Sentinel always made sure that his father wasn't around whenever Sentinel decided to mess and be mean to Optimus though Sentinel was starting to get too cocky since Optimus was never fighting back since Sentinel was still the prince and right now the Sanctum is as busy as it always is with servants busy going their chores, Sentinel being busy doing his prince training, Ultra Magnus walking through the halls making sure that everything is in order, and Optimus was just trying to not cause any trouble (you represent as Optimus Prime)
