Kim Y/N was a regular 5 year old living with her parents in the United States. But everything changed when her family decided to take a trip to Korea to visit her mother's family. Their plane had crashed and Y/N was the only survivor. Since none of her relatives wanted to take her in, she was sent to an orphanage in Korea. After the crash, Y/N didn't talk to anyone. She became a mute, rarely talking. But, her life may change and it's all thanks to an interesting group of 7 individuals.
