In Korean, shinui means faith and eui seon means great doctor. In Korean pronunciation, eui seon sounds a lot like ui-shin as if some syllables in shinui have been transposed. This pun (or spoonerism) is contemplated by the characters. One might say that shinui is an eui seon.
When the queen-to-be of medieval Korea is badly wounded, Captain Choi Young uses a wormhole to "heaven," which is actually 21st-century South Korea, to bring back the spoiled Dr. Yoo Eun-Soo who becomes a pawn in a game of human chess.
