Minseok was supposed to be organising a wedding ceremony. Instead, he's organising the Four Points to put down a rebellion. With everything and everyone he loves standing on the trapdoor, he's about to show the Four Points why they really call him 'Frost Gem'.

Luhan is a prince of the Eastern Provinces on a mission to win the hand of the "Frost Gem", the Northern Provinces' beloved prince Minseok (Xiumin during official business). Minseok always issues the same challenge to all his potential suitors, and Luhan is no different: he must be accepted by Minseok's two Guardians, a Dragon and a Serpent. Luhan thinks he could be royally screwed.
