I am not happy with romance between kids... I hope we get a bit of a timeskip before this progresses to anything weird, especially since she really is not much of a kid anyways.
I am also hoping for her past live to become a strength at some point and not just some source of trauma that she is unable to share due to not just the fear of being judged for suffering but also the fear of being used as a tool for the use her specialness as a reincarnate that knows the future brings.
