It's a waste when the isekai/reincarnation/etc. don't make the original body and its relationships a more impactful part of the story. For me that's the most interesting part of those tropes, especially since this one reincarnated into a full-fledged person with its own history, not a child. The stakes just feel so low and so bland when they already know it's him, and nothing of the original body adds some spice. It feels like this story still could've happened even without the body switch
