Please recommend a novel that is similar to the transmigration theme.

The female protagonist, a Harvard student (not necessarily a physicist), transmigrated to a useless young lady (a junior high school student, rich family). The transmigration method was a high fever.
The original owner (Miss Trash) had an adopted daughter at home.
The clip was roughly:
The female protagonist and her adopted daughter went to visit their grandparents with their family. The adopted daughter played a Canon, while the female protagonist played an E-flat major song.
