Someday or One Day (2019)

In 2019, 27-year-old Huang Yu Xuan yearns for her missing boyfriend Wang Quan Sheng, presumed dead for two years. On her birthday, she wishes to “see him.” Meanwhile, in 1998, 17-year-old Chen Yun Ru pines for a boy who doesn’t share her feelings. Her birthday wish is to “become the girl Li Zi Wei loves.” A mysterious cassette player transports Yu Xuan into Yun Ru’s life as she awakens in the past, facing a shocking twist—she’s now high schooler Chen Yun Ru. The person beside her isn’t Wang Quan Sheng but Li Zi Wei. Stuck in the past, living Yun Ru’s life, Yu Xuan must prevent Yun Ru’s impending 1999 death. Li Zi Wei, her new classmate, unexpectedly develops feelings for her, complicating matters as his friend Mo Jun Jie also harbors a crush. Can true love transcend this seemingly insurmountable time gap?
