Werewolf King's Hidden Heir

Human girl Nellie, drunk, stumbles into werewolf king Clifford's territory, has a one-night stand with him, and flees. Five years later, she applies to be his family doctor for her sick son Brady—only to discover her employer is the man from that night. Recognizing her, Clifford relentlessly pursues her while Brady's werewolf blood awakens. Werewolf nobles repeatedly frame Brady as a "cursed child" and try to kill him, but Clifford protects his family. At their wedding, he exposes the conspiracy and proves Brady's pure lineage. Nellie accepts his proposal, Brady gains the pack's acceptance, and the three live happily ever after.
