Ex-husband, how could you not know I'm a divine doctor?

I gave up my god-tier surgical talent to live as a submissive wife, only to be cast aside by my cheating ex for his mistress and their illegitimate son. Later, when that boy needed my one-and-only treatment, he deliberately injured my operating hand, and the child died because of it. In the end, I laid bare every dirty secret he and his cruel family tried to hide, and they were left to sink into unbearable regret.
