I Couldn't Protect Her

Dean is a young neurosurgeon who lives by himself in a lonely street with one or two neighbours, when a new neighbour moves into the house right across from him. He's intrigued and goes over to meet them. He first meets a nice, militant man, and then he meets a beautiful girl, who couldn't be older than Dean himself and he immediately wants to get to know her, but she's keen on not letting anyone in and immediately shuts Dean out. She doesn't believe in taking favours either. Later, when her father needs Dean, will the girl allow him to help? Or will she risk her father's life?
