One Night with the Werewolf Prince

"The girl was locked in a small wooden cabin in the woods, where she became intimate with the werewolf prince during his heat. She later gave birth to a baby boy named Beibei. Six years later, Beibei began to grow a wolf tail—a sign of his wolf lineage. However, the hospital diagnosed it as a case of atavism and insisted it needed to be surgically removed immediately, otherwise it would threaten his health. The girl worked desperately to earn money for the operation. Little did she know that the werewolf prince had been searching for her relentlessly. And their son Beibei, who inherited the blood of the wolf king, was destined to be the next ruler of the wolf pack."
