A free-spirited singer whose love of music has him performing on the streets, Kang In Soo’s life revolves completely around music. Supported by his friends, In Soo hopes to someday turn his love of music into a full-time career, but doing so isn’t easy. Refusing to give up on his dreams, In Soo continues busking, day in and day out, while his best friend, Choi Min Sung, records his performances and uploads them on YouTube. Little does either of them know that In Soo’s performances have caught the attention of someone who could change the young musician’s life forever.
A keyboardist working at a major record company, Yoon Sang Yi is always on the lookout for new talent. After stumbling upon In Soo’s videos, Sang Yi has become one of the singer’s biggest fans.

As the two live and work together, their relationship grows, and slowly, new feelings begin to blossom. Unfortunately, as their feelings grow, so do the obstacles that stand in their way. Will In Soo and Sang Yi be able to find a way to overcome the trials before them or will their love fade before ever having a chance to fully bloom?
