yeah, it will be such a waste if this turns out bad.
Hwarang was quite soapy for me, so I'm keeping my expectations low. Even the novel doesn't have much plot - the first half is basically her talking about characters and NM, being quirky and all. the second half has 4 things only - the high school, rice cake, blood relations, NM, and husband. that's it. (wrote in a way it wouldn't be a spoiler) I think that's why they are adding this murder mystery and the crowd-pulling cast...
If you look at this series, the hellish heights are just accidents like traffic accidents that don't discriminate between good and evil people, but the fact that only Jeong Jin-soo and Park Jeong-ja were resurrected seems to have been chosen to show what kind of life good and evil people live in hell.
