A mute girl, Century, was living a cruel life in her guardian's custody. She was a victim of physical and mental abuse. That changed when she returned a man's (Jin Aragon) stolen wallet. Still delighted about the mute's help, Jin then asked his up to no good son, Luke, to look for her. Luke found her in bad shape and was terrified to know about how she was treated. The Aragons then decided to let her move in their home. During her stay, Luke found out about the drag races Century was joining. He and his friends were also into it but didn't expect a mute girl to be in it. Behind Century's lack of voice, she got brains and skill in racing. Slowly, Luke was being affectionate towards the girl she saved.
