Not every happily ever after looks the same in anime, but they're always well-earned after much internal development and external conflict. Some couples' Happily Ever Afters cluminate in a grand wedding and future plans. Some are more of a Happy for Now, because their stories have an open ending which invites the possibility of other adventures, though the audience gets the sense that the couple will be happy together.
