Ok leaving aside that the story end with them fucking in the air... in the side stories they end trying to jump to another "normal" dimension, right? Even if the uke could lost his memories they were sure they meet again... So in the last panel they smile because they reencounter and live happily ever after?
I think the characters lacked a bit of depth in the end, for example, what exactly Hwa's abilities were or what his past was like. Overall, it was a good read, and the reunion in the next life, with less difficulties, was touching; there was even a hint that he remembered their previous life.
