Royal Happy Event: the Emperor and the Empress Want to Reunite

Other people's time traveling is done alone, but our family's time traveling is done in groups! Other people's childhood sweethearts are all childhood sweethearts, but ours' best friend, the Emperor, knows magic! The queens of other families fight in palaces and houses, but the queens of our family fight each other! The emperors and empresses of other families all play the piano, the harp, and the music! Our harem is full of chaos every day! Other people's other worlds are all about fighting with cold weapons, while our imaginary dynasty cannons and mines blast us!
