My Ceo's Wife, Who Was Terminally Ill and Misunderstood Me, Cried Like Crazy

The Female Protagonist Misunderstood the Male Protagonist, and After Killing the Male Protagonist, She Learned the Truth and Regretted It, Asking for Forgiveness.

I want to watch something similar to "Male Supporting Actor: After I left, the heroine regretted it beyond measure!" Book.
