It began okay - the CGI was a bit cheesy and the male lead's hair in the historical era looked ridiculously fake, but it was nothing extreme and easy to overlook those small details.

My main problem was the advancement of the love story. Sure, she's his past love reincarcerated, great, but she has no idea about the past, so how did she even fall for him so quickly? Their romance was just far-fetched at best. Even in their past life romantic scenes, there wasn't much depth to their love. When it comes to this point, I would typically stay for the second-lead's stories, but in this drama, the second leads were nothing but filler characters.
