Serena, a resilient anesthesiologist, once loved Ethan—a cardiac surgeon who forgot their past after a car crash. Reduced to his secret lover and treated like a toy just to stay close, she flees, only to discover she's pregnant. When Ethan relocates to her LA hospital, engaged, she is forced to see him again and be around his fiancée. As Ethan rediscovers their history, she’s forced to choose: escape, or risk her heart again with the man who once erased her.

You Are My Antidote

Episode 1 might make you go "what IS this lunatic" and bail. He's my favorite short-drama actor and even I hesitated. Please stay with it!! The acting is unreal, the way his eyes go, the way he smiles, each one gets me >_<

My favorite of his modern-set work and honestly my favorite short drama full stop. You get the complete unhinged-psycho performance, and I'd say his acting leveled up here. If you're working through his filmography, this is the one.
