Just another lame story that's more interested in showing girls with dark hair crying actually all the fucking time 😂 than it is with writing a narrative that makes sense.
The writer invents some half-assed excuse to have the girl tremble and shake when she's going to the past, then she cries a river thinking her father is dead while we all know very well that any blonde female character would have been allowed to stay calm under the same circumstances, and to top it off she's going to enter into this ridiculous plot to become a Joseon woman just to see her father a few times.
I've seen some inane and nonsensical plots in stories that only exist to have nutcases enjoy seeing dark-haired women weep, but this takes the cake.
