I just read the Author other works (Reiwa no Dara-san) and since their art looks really good I got curious and checked their past works, and when I found out that they previously work on doujinshi such as this I was like "Damn that explained how they have good body anatomy understanding".
Then I tried to give it a read, and surely enough I didn't expect the story is this great. I really like this alternate fan made ending for Reiko, instead of the original ending... this doujinshi actually deserve more than it is.. (The art are great, and the story are even more great). And honestly didn't expect it to be this wholesome.
Thanks for the chapter, and also thanks for the scanlator for bringing it here (the scanlation works are clean and tidy, great work!!)
