OMG...WAIT THIS MAKES SENSE, i've never thought of it like that. I just thought maybe he "lost his memories" like the cliche story or like they met as kids? And they talked abt mc's interests thats why ml knows what he likes like some another cliche story. BUT putting it into this perspective would be such a GOOD plot for the story but does that mean the ml knows what he's done before? Cuz like he keeps saying "i was waiting for this" or like "we've met again" stuff. BUT OMG THIS IS SO GOOD
Oh no. I'm sure the story is just those typical reincarnation, went back to the past kind of plot. I just thought of the marvel multiverse plot for humour.
Ugh no would love a good plot like this though.
Your dreams are the you in the other universe.
In the other universe, you were not happy.
