The two female leads are happy-go-lucky, although one was very young with the garland still on her head and the other was/is only reaching womanhood at the start. While some of the story plots diverges from each other a lot is still the same, it also seems to be around the same time period.
Both are period dramas based on an impeding war that could ruin their country’s current dynasty, while also filled with romance and the MLs spartly struggling with their budding romance over their duty.
