You might have forgotten me, but I haven't forgotten you."
Seu (Kim Seo-ah) is a talented and spirited architect who believes in logic and blueprints, not fairy tales. Her life is perfectly structured—until she visits her brother, Junu, in the hospital after his motorcycle accident.
On her way out, she literally crashes into Dr. Choi Hyun-woo, a handsome and brilliant surgeon. But before she can even apologize, he looks into her eyes with a radiant sparkle and utters three words that turn her world upside down: "I love you."
Confused and convinced he’s lost his mind, Seu laughs it off and walks away. Little does she know, this wasn't just a random encounter.
The chaos truly begins when Seu returns to her architecture firm, only to find that her new, strict CEO—Choi Sun-woo—is actually the older brother of that "crazy" doctor!
As Hyun-woo relentlessly chases after her to reclaim a past she can't remember, and Sun-woo keeps her buried under hospital renovation projects, Seu finds herself caught between two powerful brothers.
Was Hyun-woo's confession just a moment of madness, or is there a deep, hidden connection from their past that Seu has long forgotten?
A story of lost memories, workplace rivalry, and a love that refuses to be ignored.
