"Tawawa on Monday" (月曜日のたわわ, Getsuyoubi no Tawawa) is the first volume of the Tawawa on Monday doujinshi series. It introduces Ai-chan and Onii-san.
==Synopsis==
===Main chapter - Ai-chan part 1===
The reader is introduced to Onii-san, waiting for the train to work on yet another gloomy Monday. He even mentions the desire to throw himself off the platform under the train. However, he explains things have turned for the better lately. As Ai-chan joins Onii-san, we learn that this is how his Monday routine looks like these days, and Ai-chan being the source of his happiness.
Onii-san then recalls the day he first met Ai-chan, which was also a Monday. Ai-chan ended up tripping on the chairs, falling breasts first into Onii-san and knocking him unconscious. After being dismissed from the hospital with minor injuries, Onii-san got to know Ai-chan better. He learned that she rides the early Monday morning train to be able to attend school club meetings. He ended up forming a pact with Ai-chan where he rides together with her on Mondays to protect her from potential perverts on the train. Onii-san implies he and Ai-chan have done things best left for imagination before admitting that she is way out of her league, and describes all the ways why Ai-chan is the ultimate object of desire ("if youth took a physical form, it would look like her") but also almost too perfect. 
As Ai-chan prepares to leave at her stop, she notes that she should thank him somehow and cheer him up. Because it's too early to do something to cheer her up properly, she instead gives her a button that popped off her shirt the previous week as a keepsake to remember her by. Ai-chan teases Onii-san that next week her nickname will change from Ai-chan to Jay-chan because she's about to grow out of an I-cup and into a J-cup.
=== Bonus content - P-Manga 1 "Trademark" ===
(JP: 辮子醬的1P漫畫①「註冊商標」)
The manga page introduces Ai-chan, who is called Amikomi-chan in all of the bonus strips for some reason. It is first said that her trademark is her bob haircut (definitely not her large bust). Then a button pops off her shirt, and the narrator admits that maybe her trademark is her large bust after all.
=== Bonus content - P-Manga 2 "A story on August 13th" ===
(JP: 編込みちゃん1P漫画② 「8月13日の話」, 8 Tsuki 13-nichi no hanashi)
Ai-chan's schoolmate shows her a bottle of facial lotion which is a product of her father's company and wants to know her opinion about it. Ai-chan mistakes it for a personal lubricant used on her cleavage, and tells others she's relieved to know she's not the only one using it, and notes that using saliva for lubrication is embarrassing.
=== Bonus content - P-Manga 3 "Outstanding Talent" ===
(JP: 編込みちゃん1P漫画③「逸材」, Itsuzai)
Ai-chan sits on Onii-san's lap watching television as he asks her about "skirtchasers". She answers that she does get a lot of attention, inviting her to a hotel or even asking her to become an AV actress.
=== Bonus content - 4-Koma "Conversation" ===
(JP: 編込みちゃん4コマ① 「会話」, Kaiwa) 
Ai-chan's breasts are making various onomatopoeia related to bouncing. She tells her own bust out loud to "calm now", making onlookers note she's talking to her own breasts.

(JP: 編込みちゃん4コマ② 「月曜以外のたわわ」, Getsuyō igai no Tawawa)
Ai-chan is riding a train, and sees a passenger next to her type a tweet about her "too big" breasts, also tweeting how she looks like "real-life Ushio the Enchantress, just not in sailor outfit" in a likely reference to the Kantai Collection character Ushio. Ai-chan doesn't understand what this means and pulls out her phone to search for it.
