Her perfect otaku sanctuary had one problem: the walls—and her neighbors—just disappeared.
Rinko is a 24-year-old office worker and secret otaku whose favorite part of the day is escaping home to enjoy anime and manga in peace. That peaceful routine comes crashing down when a hole suddenly connects her apartment to those of her two neighbors: the friendly and mysterious Satsuki and the decidedly less-friendly Usada, who just happens to be the creator of Rinko's favorite manga. With her private hobby exposed and her life unexpectedly tangled up with two very different men, Rinko finds herself at the center of a hilarious and increasingly complicated romantic comedy.
