I love how they brought a religious so called bad guy into reality . Also really like how the writers included to bring back Min Heyjin or Heyjin Min back and use her for more of the story . And for me the love at the end they show how willing the parents were to protect they own child and die to save that child . And what saved that child was love which kinda reminds me of Harry Potter how Lilly and James loved Harry and how Lily reminds me so much of the mother in this show because once you give birth to a child for some or for most of mothers they would never want to let go and no mother would ever want there child to newborn to perish . Furthermore even though this is a science fiction show it includes many real life aspects and was just perfectly planned and organized this show and was just so entertaining to watch maybe Emmy of the year or drama of the year in korea 🇰🇷 😊😁😌😀
