I'm glad I finally found this manga on Dynasty; I couldn't find "Himawari-san" anywhere and it was only a chance Discord link that led me to "Miss Sunflower." I've been following the artist on Pixiv and always thought the pictures of Himawari-san and Matsuri and the rest of the girls were all very cute, so I took the chance to binge-read it in 3 days (would have been less without schoolwork). Thank you to the translators who kept this alive over the years!

Well, damn... We all know how good this series has been with callbacks to earlier chapters and all such clever composition, but nothing quite blows the mind like starting to re-read it and realizing that the very first volume essentially starts with a huge hint for Himawari-san's actual name.
