hey I haven’t read it yet but I did look it up and you can find it here (?) I hope this is what ur looking for!
https://mangabuddy.com/nibiiro-no-hana-gou/chapter-0-1-vol-1
it’s also on hitoma.la if you look up nibiiro no hana/ the authors name
Waaahh you actually found it! THANK YOUヾ(☆▽☆) I google searched it and mangago did have it but now the page is removed
yeah!! i remember seeing it on manga go but they removed so much incest/shota content unfortunately （￣へ￣）
Wait wait, when did they??? I guess it's because of shota not really incest because incest tag is still up but shota content is mostly gone me thinks.
the big shota cleansing around 2021-now lol it's sad because it used to be it's own tag on mangago
I guess I got into it too late but I see now it's really gone... myreadingmanga still had tons but it's also gone too (〜￣△￣)〜
You all this is not the first part, I swear these are the extras! I remembered it actually having some kind of plot starting from when they adopted tsubaki when his parents died and their whole family clan is into incest and that the 3 of them are the only remaining members of the clan so it ends with them but I forgot the order of the series and if basing from the cover photos of related artist work I think it's not there(╯°Д °)╯╧╧ I went to MRM and it's not there too(?) am I tripping or something? I swear it exist The panel of kid tsubaki wearing that gorgeous kimono for hinamatsuri, and a kid had a crush on him and thought that he was a girl lmao (they became classmates and best friends I think) BUT SEE THE PLOT I SWEAR IT EXISTS!
