Possible angle for Okarun's future development
So, main goal of previous saga or however we want to call it was Okarun "growing" some balls or literally regaining them as they were stolen. Physical glow up is there, we saw the how he performed at the exam etc, now it's time for mental development. He himself admits that he lies, now he's being hunted for his fairy tale power (whatever that is) which is Pinnochio and it's about time truth to be told. But what if by the time he gets his shit together, he realizes how bad Momo's treatment towards him was? Even before amnesia she didn't want fully acknowledge her feelings and put everything on hold after the confession at the end of Danmara. Part of growing up is realising that not everything is going to work out as we planned so him drifting apart from Momo would be a perfect way to tell that. First love rarely lasts forever after all. Which makes it even more interesting considering how Aira matured since her intruduction, now that she actually made and effort to get close to him
