I created a feeling of the past by making it an old diary decorated with pieces of old paper, tapes, and stitches between the pages because it's based on a hypothetical future scenario reminiscing about the past. To create a feeling of the dialogue and distinguish the "past"(with the sea, beautiful) and the "current"(without the sea, hopeless), I made every sentence by the child in a darker and more desaturated background and the sentences by grandma when recalling the past in a brighter and ancient style background.
