What's the name of that one movie that was all in japanese and it had this girl who's mom was sick so she randomly went off and somehow time traveled to around her dad's time (I think it was her dad) and she had been trying to get him t come home with her before he died in a bus crash but he went off somewhere in the bus and died anyway, so when she got back to her own timeline someone had told something like "you shouldn't try and change the past to fix the future" or whatever I remember watching it when I was like nine or eight, I just can't remember the name of it
