I just happened to randomly find the show and I’m glad I did. I do not know a lot about Korean history though it said this story was inspired by historical fact. Either way the riders created a very cute and entertaining story that was told in a short amount of time.As someone who is not very good at math myself I found it very funny that the basic knowledge of high school math was able to help her in that time period.I don’t know if the two leads had a lot of chemistry but somewhat believable for a story told in two hours. I wish they would’ve explored the Relationship between the secondary leads because it appeared they had a connection as children but it’s never fully explained. I couldn’t tell if they were romantically connected or not.
