The Mermaid Queen

After experiencing Alex's guidance, the mermaid girls had all fallen in love with him, deeply infatuated and unable to extricate themselves from their feelings. They had been immersed in stories of princes and mermaid princesses since childhood and had never encountered the opposite sex.

Upon meeting Alex, they naturally cast him as the prince, while they themselves assumed the role of the mermaid princess deeply in love with the prince, willing to sacrifice everything for him. For Alex, they were even willing to give up their lives. Regardless of how their mother treated Alex, they would remain steadfastly loyal to him, even if it meant going to war against their own mother. This was the power of love.

Furthermore, these mermaids had fallen under Alex's spell. Each one was unwittingly under his control, unable to resist his allure.
