Well, I am going for the realism. Ainz is in an unknown world, doesn't trust anyone yet, going through nightmares, clashes of multiple personalities, emotional suppression doesn't activate properly, also thrown in world in a human body with humans powered by god's that genuinely could end him with wrong move, no friends or allies and some gods that may see through his deception, beauty turned curse. At this point, going against the flow, or gaining attention is the last thing he want to do. But he will get dragged eventually.
