那天，她结束了一天的工作，走进浴室准备洗澡时，却发现里面已经空无一人。她打开水龙头，热水如同春雨般洒落……在这个刹那间，她突然意识到浴室上方的玻璃窗户被打开了，有个身影悄然一闪而过。她的尖叫声在空旷的空间中回荡，她本能地用浴巾紧紧包裹自己，那种屈辱感像潮水一般涌来。
她心神不宁地穿上了衣服，糊里糊涂地骑上自行车回到家。丈夫此时正在单位上夜班。从此之后，她变得郁郁寡欢，每当看到男同事，都会不自觉地想象他是否是那个窗户边闪过的人。而到了晚上，她便失眠了，无休止地思索着那个身影和窗户之间的情节。而且，不论白昼还是黑夜，只要有微光透入房间，她都必须拉下所有窗帘才能安心。
她的改变最终被丈夫发现，他轻轻拥抱她，问：“发生了什么，我可以分担你的痛苦吗？”她躲藏在他的怀抱中，说：“我告诉你，你不要责怪我。”然后向丈夫讲述了整个事件。丈夫听后震惊又迷惑，看着她说：“让我知道是谁，我一定要教训他！”然而，在片刻的沉默后，又问：“那是哪天的事？”她回答了日期。丈夫翻开床头柜上的日历，一页一页翻阅，然后拍打脑袋说：“啊，那个人应该是我！”她吃惊地说：“怎么可能是我？” husbands say with a grin: “I remember it clearly, that day I was just assigned by the director to turn on the water valve outside the bathroom, and I had no idea there was someone inside.” She sat up straight in shock, then burst into laughter as she realized her husband's innocence. From then on, it was her husband who lost sleep.
One day when he went to work without telling her, he used an electric welding gun to weld iron plates over that window. No one knew why except for her who understood its significance. But another secret she would never know: Her husband didn't go near that water valve that day.
