The drama felt like it was held together with duct tape. There was this missing spark to make the twins plot work. How are we supposed to buy into this twin dynamic when there's no connection?Somehow, the dead twin had a better chemistry and her replacement twin never worked despite being the same actress. The romance as well suffered because of that, incompatible by design. Out of all the ideas that can be spun from a twins plot, they kept it very simple while doing the bare minimum to fill the episodes. Which also resulted in long draggy uneventful events. On another note, out of all of Jin Se Yeon historical roles, this is her weakest performance yet.
