This series really wasn't as bad as some have said here. Overall, the series is well-acted by everyone with an interesting and fun romantic narrative and very strong visuals and cinematography. But, that being said, there are some obvious weaknesses in the actual story that left some unfulfilled potential, which is, what I think, are the main reasons why some have complained.

The fantasy through-line about the Naga and its connection to the main characters wasn't as strong as it could have been. I felt like they were trying to draw a sort of karmic line between Lin and the woman who's soul is trapped by a past sin. This type of narrative works best when there are strong parallels between the characters, their circumstances, and their choices in the past and present. They tried to tie it together with the motif of jewelry making, which I thought was really interesting as object symbolism, but without a stronger narrative connection between these two lives and time periods, it left us unsure what the overall point of this storyline was.

Setting that all aside, the characters are all fun and the overall romantic plot is entertaining. It's not too complicated and works for what's presented. If I had to make suggestions, I'd just go with the above in terms of development as I'll always say that strong themes and characters make for exceptionally compelling storytelling. But this series really isn't that bad, especially if you're looking for something light to watch.

I'll also say that I'm happy to watch anything that features GL as I do think there is a disproportionate amount of BL compared to GL. Equality, people!!! I want to see it.
