i stg this sounds like a drama
I don't remember the name but is it the manga about two old people, they live with the family of their child and already have a grandchild (that they both love so much). And the granny tries to get a divorce because they both hate each other but then she'd lose everything she has or smth like that.
And the reason they were able to turn young again is because they fell in a magic well when they were looking for their grandchild that went missing.
maybe this extra info will help someone find you the manga? (if this is the same manga we're talking about ofc)
ah, i dont think thats what i was referring to but thanks anyways :") -- as far as i remember its a korean manhwa-- about some famous campus couple who seems to be the ideal thing got married then had a kid but both of the parent's relationship just kept on going downhill; till after a reunion with some old classmates and updating about the times began the realizations of some things then when they met up they started arguing, drunk, then something happened--- (i forgot what exactly it is) but they got to turn back in time (around college days) however they retained their memories of their marriage and everything till their present life.
Ah whoops, that's indeed another manga, sorry! They're both korean though :') hope you find the manga you're looking for!
its about a married couple with a son whose relationship wasnt working out but for some reason had the chance to go back in time togetherヾ(❀╹◡╹)ﾉ~
