On November 2, 2026, an unprecedented tsunami swallowed vast stretches of land. The survivors were horrified to discover that the water kept rising, and the ocean was about to swallow the land.
Ancient genes hidden within the human body were activated, causing all kinds of changes in the survivors.
Lou Qian has feelings for his older brother, Zheng Chongci, that go beyond those of a brother. On the night of his eighteenth birthday, emboldened by alcohol, he confessed to his brother, and was rejected, just as he expected.
He had no time to grieve. The tsunami struck the next day.
The brothers both survived and awakened their ancient genes. The older brother became a brave, battle-hardened merman, while the younger brother became a delicate and beautiful mermaid.
Just as Lou Qian is still figuring out how to control his fish tail, his older brother can already hunt all kinds of large fish with ease. He also keeps getting handsy with Lou Qian under the pretense of taking care of him. What's going on? Didn't his brother already turn him down?
