There is only one person whom Shin Minah hates the most in this world, a man named Kim Woobin. That rascal wouldn't stop to everyday, six days in a week, for almost two years. The last time she met him was about twenty years ago when they were still donning that white and navy blue uniform. Since then she promised to  herself never to have a face to face with him ever again.

But when one morning, in her adulthood, Shin Minah got woken up with just underwear inside Kim Woobin's hotel room, she has to re-evaluate her opinion regarding this rascal. Kim Woobin not only looks super HOT, but never in Minah's wildest dream to imagine how that rascal could evolve into a renowned cardiologist who happened to be in charge of her father's heart.
