One day Jong-soo rescues Jung-won, a dying woman by mere chance, and is mistaken for a talented doctor. But things get messed up as he continues to meet with Jung-won, as one misunderstanding spawns another. He ends up falling in love with her, and gradually finds himself addicted to love.

But when he reaches the pinnacle of his "success," he realizes that everything he has done so far was in vain. His love turns into poison and ruins his life.
