Hidden Sea God's Vengeance

Kaius, a sea god worshipped for three thousand years, arrives on land as a penniless beggar seeking the missing piece he needs to reclaim the Trident. There he meets Ayla, a governor's daughter facing a forced marriage to a cruel elderly lord, and she chooses him, sealing their bond with the unbreakable Oath of Salt. Soon he is summoned back to the Deep Sea Royal Court and promises to return in five days, unaware that five days below will mean five years above. Alone, Ayla raises their twins, Leon and Nari, enduring years of humiliation and abuse.
