On the outskirts of Seoul, a young man named Yu Yongyuan ( 한석규 ) runs a small photo studio taken over from his father. He often smiles and faces life calmly, and there are different photos hanging in the photo studio.
The female traffic policeman Kim Dae-rim ( Shim Eun Ha ) has to go to the photo studio every day to develop photos due to her work, so she meets the honest Yong-won. Sometimes she would complain that the door of the photo studio opened too late, and she looked so innocent and cute. They walked together under an umbrella, talked about trivial things, and fell in love over time. Both Yongyuan and Delin found themselves in love with each other out of control.
However, Yongyuan has an unspeakable secret and cannot directly tell Delin. The seasons change, and August passes. Delin, who could not see Yongyuan, wrote to him and tucked it in the crack of the photo studio. In the snow in winter, Delin saw her own photos in the closed photo studio cupboard.
