In Ancient Rome, where the gods are real but rarely seen, Y/N lives a quiet life in a small coastal town with her family. Everything changes when she survives a deadly storm and catches the attention of Poseidon, the powerful god of the sea. Drawn to her kindness and spirit, Poseidon begins visiting the mortal world in disguise. As their bond deepens, Y/N finds herself caught between two worlds: the dangerous, immortal realm of the gods and the ordinary life she has always known. Complicating matters is Felix, a loyal young merchant who has loved Y/N for years and hopes to marry her. While Poseidon can offer divine power and eternal devotion, Felix offers something a god never can—a normal human future. As rumors spread, the Olympians take notice, and Poseidon’s growing love begins to affect the seas themselves. Y/N must choose between a mortal life with Felix and an impossible love with the god who rules the ocean, knowing that either choice could change her fate forever.
