Seven years later, Poseidon disguises himself as a wealthy mortal noble named "Payson" to pursue Chloe, who now works as a handmaiden in his temple. However, terrified of divine punishment for the forbidden love between gods and mortals, Chloe repeatedly rejects his advances. Their romance faces immense obstacles. They must navigate the jealousy and schemes of Dora, a mortal noblewoman. Furthermore, Poseidon's mother, Rhea, fiercely intervenes, and his divine fiancée, Amphitrite, goes so far as to cruelly torture and disfigure Chloe. To protect Chloe, Poseidon is willing to renounce his godhood, endure heavenly lightning strikes, and make enemies of the gods. In a desperate bid to save Poseidon's life, Chloe agrees to marry Kael, a mortal nouveau riche. However, when Kael drugs and attempts to assault her on their wedding day, Poseidon arrives just in time to rescue her, leading to their passionate reconciliation and union. In the climax, Poseidon uses his formidable divine power to defeat Zeus, who tries to use the situation to execute him. Upon discovering that Chloe is pregnant with Poseidon's divine child, Rhea finally accepts that their union is destined. Forced to concede, Zeus abolishes the ancient law forbidding love between gods and mortals. The story concludes with a grand beach wedding for Poseidon and Chloe, bringing the tale to a happy ending.
