Synopsis:

So now that means roommate? Rinko, a 24-year-old office worker, lives alone and is a secret otaku. One day, her apartment is connected to the two next door through a hole in the wall.

In the room on the left lives an innocent-looking but mysterious boy, a little too sweet for Rinko.

In the room on the right lives a boy with violent tendencies, just as mysterious… But wait! “I think I know him.” Rinko’s only privacy lies in her upside-down apartment. Now, every day is filled with heart-pounding surprises!
