Pardon the Intrusion, I'm Home!

Rinko, a 24-year-old office worker and self-proclaimed otaku, lives in her apartment alone. Her life changes when her apartment is unexpectedly connected to the neighboring rooms through a shared wall. A young man in the left room is friendly and courteous, while the person in the right room has a more aggressive demeanor. Rinko's daily life is disrupted by these new roommates, particularly when she recognizes one of them from a past encounter.
