Stand By Me Doraemon 2

Nobita travels back in time to see his grandmother, who died when he was very young, and her wish to see him grown and married sets off a chain of complications involving his own future wedding day. The film moves between past, present, and future as Nobita attempts to fulfill a promise while an adult version of himself develops cold feet. It leans harder into sentiment than the franchise's usual adventure structure, aiming squarely at the emotional weight of family across generations. Every timeline he visits complicates the promise he came back to keep.
