Trivia / Someday or One Day

• Acting for Two:
  • Alice Ke plays both Huang Yu Xuan and Chen Yun Ru.
  • Greg Hsu plays Li Zi Wei and Wang Quan Sheng.
  • Xie Zhong Ru and Xie Zi Qi are both portrayed by Kenny Yen.
• Bonus Material: A video was released to thank the fans for staying loyal (and watching legal broadcasts) after the Content Leak. Set after the ending, it depicts Zi Wei's 28th birthday, where he celebrates with Jun Jie and an older Yu Xuan (who may or may not be part of his imagination rather than the real thing).
• Content Leak: An early version of the final episode was leaked in Mainland China a week before broadcast.
• Dawson Casting: In effect with all the high school-aged characters, though special mention with Huang Yu Xuan (27 years old) and Chen Yun Ru (17 going on 18) being quite younger than their actress Alice Ke (who was 34-35 when the show was airing).
• Revival by Commercialization: While all of the licensed music used in the drama experienced an uptick in popularity, Wu Bai's "Last Dance" had the greatest resurge thanks to the song's prominent role in the story, ending up in the top 5 of Chinese music charts after the broadcast.
