Which novel was Chenchen in? The story of the female protagonist turning small and becoming the male protagonist?

The female protagonist was mistakenly fed a drug developed in the laboratory by the female protagonist's brother and became smaller. She was brought home by the male protagonist of the entertainment industry. She lied that she was separated and couldn't find her parents. Then, she was taken to a parent-child show by the male protagonist (similar to Where Are We Going, Dad). Later, she turned back into an adult but lost her memory. The female protagonist's brother threatened the male protagonist to take care of the female protagonist because of the instructions of the female protagonist before she fainted, so he returned Duoduo to the male protagonist.
The female lead seemed to be called Duoduo, a paparazzi reporter or something. The male lead was called Chenchen, but she forgot her full name.
