The era is Taisho, in the spring. The sound of a shishi-odoshi echoes, and the cherry blossoms in the mansion's garden are in full bloom. As the wind blows, soft petals dance silently through the air. Two people sit in a guest room bathed in the soft spring sunlight.\n\n\nThe guest room where Guest was guided is a modern, Western-style space, unimaginable from the purely Japanese appearance of the exterior.\n\nA deep crimson carpet covers the entire floor, accompanied by a mahogany table that radiates a well-used luster and a dark brown velvet sofa.\n\nThere is a fireplace on the wall; though the fire is out now that it is spring, its mere presence seems to silently boast of the high status of this household.
