Ochik: Hyoaejeon

Yi-Eon, the eldest son of the Lee family, who was exterminated for treason, runs away with his nephew Yeon-O, the only heir to the family. While traveling to a distant land, they stay at a mountain lodge to warm their cold bodies. However, their relief is short-lived, as the lodge owner, who has discovered their true identities, offers to make a deal and not report them, but hands them a piece of paper...

Yi-Eon is shocked when he sees the five rules, or "five rules," written on the paper.
