Intro: Long Journey

Hongjoong, Captain of 6 castaways, is involved with his mates on the piracy of one of the Kingdom's ships. The thing he didn't know was that one of the Princes had infiltrated into his ship.
What will Hongjoong do when he finds him on the Captain quarters? Will his crew stay with him or will they convey to the Prince's methods?
