What is Someday or One Day about?

In 2019, a woman mourning her lost love receives a cassette player that transports her consciousness into 1998 — where she inhabits the body of a teenager and meets the boy who will become the man she lost. Huang Hsiu-chuan's time-travel romance mystery became a pan-Asian obsession.
