College student Yeo Eui-joon works the graveyard shift at a convenience store to pay his bills. The shift sucks, but the money’s good, and the customers—mostly mobsters and hoodlums—don’t cause too much trouble. That might be due to Gunwoo, a tall, hunky gangster who frequents the store for booze and cigarettes. He’s scarier than the rest of the clientele, but seems to have a soft spot for Eui-joon, defending him from the more volatile customers. Could there be more behind Gunwoo’s protective actions? And if so, is Eui-joon prepared to be a part of Gunwoo’s violent world?
