Kim Jinwoo is a small 24 year old with high ambitions, and a tendency to get lost in large places. Ever since his move to Seoul he has discovered a numbing lonliness that threatens to pull him into the depths of complete emptiness. As a young artist his paintings aren't getting a lot of attention from the outside world and a lack of money only makes him all the more empty on the inside. Until a young man named Song Minho stumbles into his gallery to get out of the rain, and is immediately drawn to one of Jinwoo's only watercolor paintings he has ever done. But Minho discovers the painting isn't the only thing he is drawn to.
