After Picking up the Green Tea Shark, the Scumbag Fiancé Cried

On the day I was betrayed by my fiancé and my close friend, I picked up a beautiful shark on the beach. His tears turned into pearls, and he acted coquettishly: "Sister, it hurts -" I healed his wounds, taught him how to read, and watched him smash the dowry gift of a scumbag with his tail. Until the shark pressed me against the coral couch: "A mortal has raised me for three years, and according to the laws of the Shark clan -" "It should take me a lifetime to repay."
