"父女七日变" (Father and Daughter's Seven-day Transformation) seems to be the title of a story or drama, but I couldn't find specific details about it. It might refer to a scenario where a father and daughter undergo significant changes or experiences together over the course of seven days. Without more context, it's difficult to provide accurate information. If you have additional details about the plot or source material, please share them so I can give you a more precise response.
