One day, she's assigned a property that should have been vacant—an old Tokyo house previously inhabited by owner Horio, whose company collapsed and whose fiancée abandoned him. Haruka desperately wants to sell the house, but success seems unlikely. A few days later, her husband suddenly shows up at the open house and tells her, "I want to have sex in a different place than usual." Before she can resist, he forcefully pins her down. Unbeknownst to Haruka, Horio witnesses the entire scene. Secrets lurking behind the real estate industry and the tangled dynamics of her marriage lead to a thrilling, action-packed story full of twists.
