Rinko Nakama is a 24-year-old office worker who skips socializing to rush home for anime every night, until her viewing draws furious pounding from the neighbor on one side and the wall finally gives way, opening her apartment onto both Akito Satsuki's place and Haruma Usada's. Rinko is stunned to learn that Haruma, the one who kicked the hole through, is secretly the author of her favorite manga, and the three fall into an odd new routine of shared living through the broken walls. Comedy and romance both grow out of a home life none of them planned for.
