Shin hye is a cute, bubbly girl. She is loved by everyone. But her life is not as sweet as marshmallows and candies. She lost her mom when she was just 12 years old, her mom because of cancer. Her father is the greatest dad in the world but without her mom, sometimes they are as gloomy as rainy night in the cold winter....
