목소리 or Mok So Ri is her name. It literally means 'voice'. Clearly her mom didn't put much thought into naming her. Her life has always been hard and the only happy memories she ever had was probably when she was around 5 or 6 years old. On the day she gets her college admission result, she was hit by a car but since nothing happened to her the driver just walked away until one day she met him again. Nakamoto Yuta, a Japanese exhange student in South Korea. Nothing interest him until he met her, the unlucky 'voice'. The story revolves around Nakamoto Yuta and Mok So ri, two dejected souls who found comfort in each other and before they even know it the two meant so much more to each other than they even realize. With each other support they get through their life and strive for their goals.
