[1] An original net animation (ONA) adaptation by Pine Jam aired from October to December 2016.

The story revolves around an ample-breasted high school student named Ai who has a chance meeting with a salaryman on a train and they strike up a friendship.

They meet every Monday on the train where they chat and the salaryman serves as her chaperone during the crowded commute, eventually starting a relationship.

This project was initially called Getsuyō Asa no Shachiku Shokei ni Tawawa o Otodokeshimasu (月曜朝の社畜諸兄にたわわをお届けします, "I shall offer tawawa to our brothers in corporate slavery on Monday mornings")[2] before Himura gave its current name after the 46th illustration,[3] and has since posted more than 200 illustrations.

Kōsuke Murayama directed the anime, Hiroyuki Yoshii adapted Kiseki Himura's original designs, and Pine Jam produced the series.

[11] A Blu-ray and DVD, compiling all 12 episodes, were released at Comic Market 91 (December 29–31, 2016) at NBCUniversal's booth.

Yuki Ogawa is directing the anime, with Hajime Kamoshida writing the scripts, and Tensho Sato adapting Himura's original designs.
