Winnie is a surgical prodigy who gave up her career for love—only to become a humble, insignificant stand-in for her boyfriend Cyril's first love, Camila.
When Camila returns, Cyril's humiliation and cruelty toward Winnie escalate. He treats her as nothing more than a shadow, an easy replacement who exists only to serve his needs. Winnie endures it again and again, until her heart finally dies.
She tears up the engagement contract without hesitation. Then, under the legendary name "Zero," she makes a high-profile comeback and returns to the summit of the medical world.
When Cyril discovers that the fiancée he discarded like garbage is actually the idol he has admired for years, regret floods him—but it's far too late.
Winnie achieves a perfect counterattack in both her career and her dignity, leaving her ex-boyfriend able to do nothing but look up at her from the abyss.
