The year is 2171, and in the mid of a slow death of homo sapiens on Earth, Aeric Sone, the ruler of planet Azuron and the King of the Galaxy, sends his sons, Liam and Haniel, to Earth to punish those responsible and save as many chosen ones as possible. Haniel is in charge, while his half-Azurian brother, Liam, is his assistant and responsible for their security. The brothers have limited resources and need to work with what they bring with them, as well as what they can gather using their technology.
At the beginning of their mission, they meet a young woman named Danica Waters. Liam is immediately drawn to Danica, not just for her beauty but for her kind, caring nature. She is attracted to him as well in a way she has never felt before. Liam pursues Danica in between his duties for his father and his brother, Haniel.
Azurians are different from humans in many ways, one being they are only capable of romantic love once in their lifetimes. Once they fall in love, they never will again, and the love for that person will stay with them until their death. Liam realizes Danica is his one love, and although she is human, Danica feels the same for him.
Liam wants to protect Danica at all costs once danger comes to her, and they start to work together to help with the tasks given to Liam by Haniel. Liam will stop at nothing to ensure Danica's safety, security, and bring her happiness. He is even willing to go against his brother, Haniel, to save her.
