Yuuki, my wife, who was told by her husband that she was on a business trip on the third anniversary of her marriage. Her husband tells Yuuki to go to the hotel he booked instead, "Forget the busyness of daily housework and relax." Yuuki heads to the hotel with a note in hand, feeling lonely. It was a luxury hotel, but after checking in and entering the room, strange men with masks were inside... The man gently handed over the phone from her husband to Yuuki, who was confused because he could not grasp the situation.
