I just watched the movie The Girl Who Leapt Through Time and it was beautiful. Since it's a movie with a concept of Time travel and loops questions might come up.
In the movie nearly towards the end it is revealed that Chiaki came from the future for that painting and eventually falls in love with Makoto.
After that when Chiaki leaves that present World or maybe just disappeared a few girls are show gossiping about Chiaki marrying a girl older in age.
Then Makoto leaps through time one last time to change things again and jumps in a time where Chiaki hasn't yet revealed that he came from future and Makota wanted him to express his feelings, finally Chiaki comes near her and whispers "I will meet you again".
So my question is, since Makota lives in the past relative to Chiaki as he came from the future, Makota is actually older than him, and both promises each other to meet in the future and possibly marry. It is not yet understood by me that how come those girls knew that Chiaki married a girl older in age while it was still the present day and not future.
