The Mermaid's Disabled CEO Lover

[Completed.] When Gu Chenxing wakes up, he finds that he has transmigrated into a book with the same title and become a tragic expendable character. His father brings his mistress and illegitimate child into the family home, trying to seize everything that rightfully belongs to the original character and his father, and take their place. The original character is also injected with a mermaid-inducing serum by his biological father, turning him into a mermaid capable of pregnancy. He is then forced into a political marriage with the disabled eldest son of the Bai family, to squeeze whatever value remains out of him. His scumbag father, however, has no intention of getting a divorce, hoping to enjoy the company of both women. Gu Chenxing transmigrates at the very moment the original character is forced to transform into a mermaid and takes his own life in despair. Seeing his father, Bu Yunxi, crying uncontrollably, Gu Chenxing decides to avenge the original character. The quickest and most practical way is to agree to marry the eldest son of the Bai family. The Bai family's eldest son is disabled? No problem, he can cure him! The Bai family's eldest son is brutal? No problem, this is just a transaction! The Bai family's eldest son is ruthless? No problem, he's only using him too... Gu Chenxing, who is slow to recognize his own feelings, never realizes that he is falling into Bai Jian's hands step by step. On their wedding day, Bai Jian expects his new little wife to be as terrified of him as all the other mermaids. But soft and gentle Gu Chenxing only asks him to be gentle. What's more, after their wedding night, his little wife even massages the leg that has been paralyzed for ten years, despite his own aching back... Bai Jian looks into Gu Chenxing's eyes.
