——"Why is the sea salty?"
——"Because, those are one person's tears, and she shed a lot of tears for another person."
The sharks, a strange aquatic tribe that has lived in the deep sea for a long time, have been hidden from the world for nearly two hundred years. Only because a woman from the tribe met humans, the silence that followed for millions of years was broken. Yu Yuren has a bloody hatred for human beings, but Zi Gui cannot understand the inherited resentment. She cannot stand the charm and methods of women of the same age, and does not want to do everything possible to frame a human being she has never met before, and does not want to continue the family's strict rules. So she privately destroyed the sea world and went to the human world. An encounter with a human being, for which he persistently repaired his bones and transformed into a human body, only to be met with his coldness and ruthlessness. If there is fate in the next life, who will pity this lingering relationship?
