In Korea, on one of the side streets, there is an amazing photo studio called “Rainbow,” rumored to be able to grant dreams. All you have to do is write your dream in a special notebook. If the owner is interested, she will offer to do a photo session, and then the wish will come true.
Hyun Sugeun, sheltering from the rain, goes into this studio to get a coffee. Upset, she writes her story and her dream of permanent work—without even suspecting how much it will change her life. Could it be that this photo studio will really grant her cherished wishes?
