The drama contains historical stuff and a combination of for 4 languages (Japanese-English-Mandarin-Taiwanese Hokkian) that I liked so much. Together with Aaron Yan and its 3 episodes length, those factors add extra appeal for me. Despite the different languages, I don't feel any gap between the stories and the characters are not 'disconnected' when speaking or showing emotions to other characters who primarily speaks different language. The main story itself is not complicated - you know what is the problem and you know what the outcome will be - but it is not boring. But still you will find some scenes that is not necessary at all when the drama could use them to develop more depth in the story. While I understand some of the side stories are not solved well due to the pandemic, I feel that at least they should try to do something (e.g: Letting Haruka narrate some updates about them). There also a few times they "eliminate" extra actors from the scene with a rather unnatural way which made it less realistic. In terms of music, I couldn't say much but yes I love the theme song.
