Eui-joon, a 25-year-old college student, works at a convenience store and faces daily threats from the regular customers, the gangsters. He cannot help but shiver every time he greets them, but the high hourly pay is too good to give up. One day, Eui-joon gets into trouble during his shift, but unexpectedly a man named Gun-woo pulls him out of the situation. As Eui-joon always looks forward to those who stand up for justice, he felt extremely grateful to Gun-woo. Eui-joon recognizes Gun-woo buying alcohol and cigarettes, but ever since Gun-woo bought ‘the thing,’ Eui-joon can't stop thinking about Gun-woo more than ever.
