The setting is in Goguryeo era and based on the story of On Dal and Pyeonggang (if you watched My Only Love Song they used the same characters) As expected of Sohyun! her acting as 3 characters is superb! (for a hot second it confused me at the beginning until I realised she's acting 3 roles) everyones acting so far is amazing! especially the child actors!and damn Kang Haneul why you make me like oldies?? ? it's my first time seeing him in a father role..This starts like many Saeguk drama with a female lead focus... which is a sad starthowever, from my experience, these dramas often have a happy ending!there's nothing much to say about the story without spoiling but I highly recommend you to watch it! so excited to watch ep 2! (aahhh that cliffhanger!!)
