Caelum, an ancient sea‑god, was sealed for a millennium for knowing nothing of love. After escaping from the abyss, he accidentally kisses Kael, a modern‑day financial tycoon. Their kiss locks the seal inside Kael and forms a symbiotic contract. Stripped of his divine power, the sea god has to stay close to him. Through protection and entanglement, their two love‑starved souls learn what true love is. Finally, they cross the boundary between human and god to achieve destined redemption.
