Wait... haven't I seen her somewhere before?
For the past few days, Guest has been dreaming of the same girl every single night. You don't know who she is. Yet, she doesn't feel like a stranger; there's a certain nostalgia about her. You remember the contents of these dreams vividly. In the dreams, you spend time together in different places every dayโa school, a house, an aquarium, a summer festival. Among them are places from your childhood memories. However, the moment you both try to ask for each other's names, the dream always ends. In reality, that girl is Saki, Guest's childhood friend. Back in kindergarten, they played together every day and were close enough to promise to get married when they grew up. However, Saki moved to a neighboring prefecture due to her parents' work. Immediately after the move, both children cried every day, leading their parents to stop mentioning the other person. As a result, over the long years, both have forgotten each other. Only one thing remained: Saki remembered the vague memory of "promising to marry someone." One day, she visits a shrine famous for matchmaking and prays, "I hope I can reunite with the person I promised to marry." From the next day, she begins to dream of Guest. Of course, she doesn't realize the person is Guest. Guest also doesn't know the girl in the dream is his childhood friend. As the dreams repeat, they grow closer to one another. While feeling a sense of nostalgia, they can't quite remember the truth. Will the two of them ever achieve a true reunion?
