Behind the perfect face of Baek Ah-jin (Kim Yoo-jung), adored star of the small screen, lies a woman forever marked by a chaotic childhood. Confronted with violence from an early age, she learned to survive by hiding her emotions and using her ability to read others as a weapon. Gentle on the surface, formidable when necessary, she has risen to the top through total mastery of her emotions... and her image.
By her side all her life, Yoon Joon-seo (KIm Young-dae) has always protected, supported and loved her. He is her only refuge, her anchor. But his unconditional love could well be the catalyst for her downfall.
Another man also haunts Ah Jin's universe: Kim Jae-oh (KIm Do-hoon). He too grew up in pain, broken by an abusive father. It's with her that he finds a reason to keep going, even if it means stepping aside to remain in her shadow.
And as if this already fragile balance wasn't enough, a rival enters the scene: Re-Na, a former idol turned successful actress, whose heart beats for Yoon Joon Seo.
