Love in Translation: Uncut (2023)

Not entirely the same, however the aspect of incorporating learning Chinese or Mandarin is a highlight in both of the dramas. While learning Chinese in these dramas are for vastly different reasons, they are both a good watch.
I Told the Sunset about You is more cinematographic which pulls it together more since it feels like a more serious drama.
Love in Translation is truthfully a feel good drama, with some serious topics and scenes thrown in.
Both are great though!
