I think I cried almost every episode. The entire cast was a master of portraying unbridled emotion. From the kids to the adults, all had a gravity to their performance that made me emotionally invested to the end. I haven’t cried this much since Scarlet Heart Ryeo. Just a stunning gem of a drama. Hit all the classic tropes of a sageuk: the politics, the scheming prime minister and dowager Queen, the unsuitable love interest, the second male lead that you cheer for until the end... but all are done well. Throw in a bit of the supernatural to allow our main character to return from the dead and emotions run high. Definitely worth watching.
