Mr. Yan

The fat and ugly Nora Smith is the laughingstock of the town when her fiancé breaks off their engagement.
He says, “The sight of your gigantic face and thunder thighs disgusts me! Don't ever pester me again!"
“What an idiot.” Nora scoffs and turns around, her lips curling up into a smile. 
Later, when Nora successfully slims down, she returns as an astounding beauty.
Her ex-fiancé comes to her bearing flowers and begs, "I was wrong, Nora. I’m willing to do anything as long as you come back to me.” Nora rests her chin in her hands and smiles as she replies, “Real men don’t dwell on the past.” Angered, he says, “You’re just a dimwit saddled with baggage that I dumped, Nora. No one will want you except me!"
But following that…
A young and popular singer tweets: “Nora Smith is my goddess!"
An internationally renowned surgeon asks, “Are you free tonight, Nora?”
Even the rich and influential hotshot whom everyone is scared of comes forward and says, ”I can take care of my wife and children myself, thank you very much.”

She Becomes Glamorous After The Engagement Annulment

Angela watched Anthony pass her by to finally stop in front of Nora.

He bent down and offered her the roses in a gentlemanly manner. "Miss Anderson, may I have the honor of becoming friends with you?"

Angela's eyes widened in astonishment as she stared at the scene in disbelief.

The light in the bar was a bit dim, which made her feel as if she was dreaming. Why had Anthony gone up to the damned fatty?

Nora didn't expect such a dramatic twist, either. She had only met Anthony twice, yet he had dumped his prospective fiancée to woo her?

But when she saw how surprised and furious Angela looked—to the extent that it made her look rather savage—her anger from just now calmed a little. The corners of her lips curled upward with great interest into a mischievous smile.

Her smile, which was as bright and dazzling as a blooming sunflower, made Anthony's eyes light up.
