XXL Wife is Now a Billionaire Queen

Sunny keeps house for her husband Derek, who cannot look at her without commenting on her weight. He and her closest friend arrange things between them, and the two of them put her in the ground while she is still alive. She is dug out by Noah, the man she loved before Derek, and by David, an old man with a great deal of money, and the pair of them keep her alive. She decides what she is going to do with the time they gave her back. She loses the weight, changes her face and her name, and comes back as Elena, walking into Derek's honeymoon party as a stranger he very much wants to meet.
