There was this policeman. One day he shot dead a young man by mistake. For some reasons, he was not fully responsible for his death but he resigned from the force anyway. However, he felt so full of guilt that he felt he needed to find out what happened to the dead man's family. To his horror, he found that the dead man had left behind a younger sister who was still schooling at that time. Even before meeting her, his informers have already given him some info regarding the sister and how she had been coping without her only sibling. this man felt sorry for having killed her brother, and so decided he had to be close to that girl and be her guardian angel, just as much as her brother had been to her before he was killed.

This younger sister was brought into the home of an aunt who made her work at her cafe after coming back from school. There had to be some reasons why the relatives did not seem comfortable. She really hated the murderer and had been set on trying to find out how her brother was killed in what she had thought to be an accident. Yet, although it had been finally decided as an accident, the sister had refused to forgive the man who killed her brother.

But little did she know that her brother too, had actually joined the gang to rob the bank. He was new but becos he had needed more money, his bad friends pressurised him into joining them. Unfortunately, the attempt was foiled and within minutes of his first encounter with the police, the brother was shot while trying to help his friend.
