Both take place in a fantasy world, where the characters participate in battles where magic, mythological characters (themselves) take part. The magician who is immortal, the young heir to the kingdom who has golden wings. A couple who are able to sacrifice themselves for each other (more of the male protagonist part). A frozen lake where the story begins and ends. This series has less chapter and less production than Love and Redemption 2020, but I put it as the second best drama of 2020, second only to Love and Redemption.
