“Love crossed lifetimes. Now it must cross the tide.”

 Years after their happy ending, Joon‑jae’s quiet life shatters when a red‑tide phenomenon awakens an ancient “Sea Court” that demands Shim Cheong return—or watch the land drown in debt it owes the ocean. He dusts off his con‑artist genius for one last unbelievable heist: stealing a verdict from the gods. Flash cuts: bioluminescent chase through a glass‑tunnel aquarium; Joseon flashbacks rippling over modern Seoul; a rain‑kiss reunion at a lighthouse; courtroom beneath the waves where pearls turn to tears; rooftop run as hunters with harpoons close in; Cheong’s voice faltering as the sea starts reclaiming her memories. A rival oceanographer whispers of a way out—if love pays the price first.

 Verdict: Lush, romantic, and myth‑bright—swoony chemistry, city sparkle, and ocean‑deep stakes primed to make hearts overflow.
