In the beginning, she was just his "agreed wife", earning 30,000 yuan a month and not disturbing each other. She lives upstairs and he lives downstairs. One teaches in school and the other works hard in the business world. They are loving in front of each other, but they live their own lives behind the scenes. But I don't know since when, he started to remember every dish she liked to eat, and she would leave a light for him late at night. From being respectful to each other to being frank and dependent on each other, two lonely hearts slowly get closer in the fireworks of the world - it turns out that the best love often happens in the least romantic contract.
