Fiancé Shen Yi spent twenty million to buy back a gorgeous merman, originally intending to harvest scales to make a wedding dress and pearls to cure Xia Li's illness. Who would have thought that the merman Xianxian would mistake his feeding scripts for deep affection, and even transform legs to come ashore for love. A misunderstanding brings out a "pregnancy" farce, also making three people see love, possession, and freedom in a new light. When Xianxian finally swims back to the ocean, Xia Li also welcomes her very own wedding.
