Lovers in peril amongst troubled times, and a grand wheel of fate that awaits them You told me, my little Princess, That a sworn promise must be carved into the heart, not a rock. "Swear it in front of the Gods of Heaven and Earth, that Eunri and Gyeol are now wed. Carve our names onto here." The young obedient groom, Se Gyeol, took out a pocket knife and carved their names side by side like the little bride had asked. "As our names have been carved into this rock, it has now become an oath set in stone." "Hmph. A sworn promise should be carved into the heart, not a rock, you know." The Crown Prince of Sayuta, Lee Hun Se Geyol, 13 years old The Crown Princess of the Je Empire, Dam Eunri, 8 years old A sworn promise made at youth blossoms entrancingly amidst an impure world stained with betrayals and conspiracies.
