Transmigrated to the 1960s as a Delicate Little Darling

Su Qingyue, a modern young heiress, transmigrates into the body of a twelve-year-old girl in the 1960s, with a younger brother thrown in as a bonus. Just as she is about to cry over how impossible life has become, she discovers that the supermarket she used to run has come along too. And there's a young man who looks out for her every day. So Su Qingyue, a little timid, a little spoiled, and a little willful, settles into a quiet life of sneaking food and treats.
