omg omg omg omg i just had this theory, what if the last few chapters weren't showing about how it would be if she didnt go back into the past but rather this is a parallel world which is where she came from and time didnt turn back but she's actually in a whole different world rn..... ( i have no evidence to back this up tho so it might not be true lolz, was just a thought i had when i saw the last panel of the latest chapter )
