Plot

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. The series also focuses on other well-endowed female characters and their love interests.

Concept

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") before Himura gave its current name after the 46th illustration, and has since posted more than 200 illustrations. These illustrations are colored in a blue monochrome theme. The initial purpose of these illustrations was to provide a positive motivation towards workers and students alike on Monday mornings, as the role of students and workers are reflected through the characters Ai and the salaryman, respectively. Besides Ai, the stories of other various girls and men are also illustrated every Monday. So far, the first volume illustration compilation book that also includes comic was released on December 31, 2015, at Comic Market 89. The second volume was released at Comic Market 90 and the third volume was released at Comic Market 91, all has been published by Himura himself.
