Everybody wondered why a handsome, clever, rich, and popular boy like Jang Wooyoung couldn't get a girlfriend. No one knew. Behind his strong appearance, there was a big scar that could't allow him to give a space for a girl in his heart. No one knew, except Lee Jieun, an ordinary girl that had a lot of extraordinary things.

Someone said, love was like poison, it made you weak before killing you, but love was also a medicine, it could even heal the worst scar in your heart.
