The manga originally serialized in Shinchosha’s Shōsetsu Shinchō novel magazine beginning in 2016, and Shinchosha published a compiled volume last October.
Yabe said in a message that starting the manga again was “painful but enjoyable, and lonely but happy.”
Within three months, the book had sold 200,000 copies, and has since sold 660,000 copies.
The manga is based on his real life experiences with his landlady.
