After moving from a semi-basement apartment, web novelist Lee Hajin decides to share rice cakes her mother sent as a housewarming gift with her neighbor.

This was Hajin's first impression of her neighbor. "...Wh-wh-who are you?" On top of that, she speaks in a timid voice with a severe stutter. It seems her neighbor might be a bit strange.
