SPOILER WARNING:
I would give 4-5 stars, but I'm petty that Dan Hwal decided to not carry out his revenge on Sang-un after finding out she "wasn't in control" when killing his whole family. But instead he fell in love with her, even though he saw her murder his wife and kid in the cold and dark forest, lying in their own blood. But its apparently okay to him because again, "she wasnt in control" 🤦🏽♀️.
I came here to support and watch him seek revenge for his poor family get carried out (not romance), but nevermind :/
