Only a true bride of the Sea God can quell his anger, which is believed to be the source of devastating storms. Mina contemplates the fate of the Sea God’s brides and her own destiny as she navigates the path to the shore, driven by love for her brother, Joon, rather than the desire for safety. When a storm approaches, Mina discards her sandals and runs toward a boat that carries Shim Cheong, the chosen bride and sacrifice for the Sea God, and her brother Joon. Despite being an average swimmer, Mina battles the treacherous sea to reach them.

When she reaches the boat, Joon reprimands Mina for risking her life; he has broken a sacred rule by accompanying Shim Cheong to her fate, for he cannot bear to leave her alone. Mina learns of Joon’s love for Shim Cheong, who is revered for her divine beauty yet bound by destiny to the Sea God. As they stand on the boat amidst the storm’s eerie calm, a colossal dragon, the Sea God’s servant, appears and fixates on Shim Cheong. In a defiant act, Joon stands protectively before Shim Cheong, sealing his fate against the dragon’s wrath.
