Exhausted from city life, SAKURA travels to the countryside, rich in nature. She begins working as a live-in maid at a large house with a vast garden, her heart racing with anticipation. Guided by the master of the house, she meets his son—both of whom turn out to be NEETs, showing no real difference from city dwellers. What catches her attention more is a sealed room at the end of a dimly lit hallway. Intrigued by its eerie, mysterious atmosphere, she wonders what secrets lie hidden inside. She also notices a strange scent lingering on the laundry. Where is it coming from? Who used it? Surrounded by this peculiar fragrance, SAKURA gradually finds herself drawn deeper into the mystery. Strangely, she feels curious—excited even—as an unexpected, thrilling development begins to unfold.
