Poet Jae-ho no longer can write poetry in reality so he belatedly registered on the cyber world. There, he meets Ju-yeon whom Jae-ho knew before but has not thought of for 15 years. Jae-ho came to the cyber world with high hopes but is having a hard time adjusting. Ju-yeon teaches him the laws, the rules, and the living customs of cyber world. In the process, Jae-ho and Ju-yeon go beyond the everyday talk to discover an important memory that has been pushed out. Curiously, it was a file that was drifting in the sea of the cyber world. It was also Jae-ho himself as well as something to be avoided.​
