My Foolish Husband Is A Billionaire

He was originally a billionaire, but an accident caused him to lose his memory and disfigurement. Saved by someone, he decided to marry the granddaughter of the person who saved him, in gratitude. However, when she woke up, she despised him immensely, even filing for divorce. Finally, he regained his memory and reclaimed his status as a billionaire. Five years later, she came to see him with their child.
