I remember how everyone thought we were dating exactly a year ago. Deep down, I wished the thing we had for each other was for real. When I had the chance to find out whether he was serious about me or not,

In a world segregated between the upper and the lower classes, where the upper class have oppressed the lower classes for so long, one event takes place that threatens Seunghyun's love for Soojung and his friendship and brotherhood with Jiyong.  When the world around them is changing so quickly, will Soojung be forced to choose between her love for Seunghyun or her loyalty for her brother Jiyong.
