My father was the person I hated most in the world. He was a man who couldn't keep his hands off women, and even when my mother passed away, he was with his mistress.

She earnestly pleaded, "I really want to meet your father." Unable to resist her sincerity, I gave in and took her to my parents' home—just once, I promised myself.
