Ten years ago, during the graduation party, three boys bullied a poor classmate — without realizing what kind of revenge was waiting for them years later

Ten years ago, during the graduation party, three boys bullied a poor classmate — without realizing what kind of revenge was waiting for them years later. 

Ten years earlier, at the school prom, three boys from the class decided to “have some fun” with the quiet, straight-A student. She was always shy, kept to herself, and hardly spoke to anyone. People said she didn’t have a father and that her mother worked as a cleaner. The girl never bothered anyone, but people like her often become easy targets.
