80年代にタイムスリップしたら、継母になってしまった

Julie Stein wakes up from her sleep, expecting just another ordinary day. However, to her surprise, she finds herself in the 80s, a totally different era from where she belongs. Not only is she a disowned daughter of a wealthy family to whom she has no blood connection, but she is also supposed to marry an old man with two children, in place of the family’s biological daughter.
