Summary

Living in a district that was known for its gang violence Bomi had no choice but to toughen up and fight back. Unexpectedly she had a talent for fighting and caught the attention of some gangs. Rather than being on their bad side Bomi joined them and as a result the gang began to grow in influence, becoming #1 in their district. She became ruthless, cold-hearted, and was feared by everyone. However, an unexpected encounter with a gentle upperclassmen made Bomi see what she'd become, which made her want to change. His kindness and warmth helped her to get back on the right path. When he graduated, Bomi never saw him again...

Even after becoming a university student rival gangs still come to pick fights with her. One particular day, after her classes were over a bunch of high school delinquents tried to gang up on Bomi to steal her money. Without breaking a sweat, she beat them up using only her left shoe. The delinquents although in pain, were amazed and wanted Bomi to become their leader. Obviously she refused but they kept following her around calling Bomi "Big Sis". They were persistant and along the way Bomi felt a soft spot for them. Bomi sees herself in them when she was their age and made a promise to herself that she'll do everything she can to set them on the right path. Just like her upperclassmen did for her. Bomi hopes that one day they'll listen to reason, but until then she'll watch over them.
