Pardon the Intrusion, I'm Home!

The romantic comedy's story centers on Rinko, a 24-year-old office worker and closeted otaku who lives alone in an apartment complex. Despite her busy work life, she finds time to unwind by reading her favorite manga Usaneko-bu and watching anime. But every time she watches anime, her neighbor to her right violently bangs on the wall, asking Rinko to quiet down. Rinko asks for help from her gentleman neighbor to her left named Akito Satsuki, to talk to her right-side neighbor through the wall. But the right-side neighbor ends up kicking the wall down. Rinko gets surprised when she finds out that her right-side neighbor is actually the creator of her favorite manga, Haruma Usada. Haruma also ends up kicking through Satsuki's wall as well, and a weird, new style of "room sharing" starts between the three neighbors.
