The Red Sleeve (2021)

In Korea during the first half of the 1700s, Yi San is an aloof and perfection-loving young prince. His father’s killing haunts him, although it leaves him in the position to take the throne once his grandfather – the cruel and ruthless current king responsible for Yi San’s father’s death – dies. He has resolved to become a benevolent monarch who will reform the law when he eventually takes the throne, but the way his father was killed has scarred him emotionally.
