Oshibana! - Ch. 44

[Clarinet]

BTW

Why is the English name suggested as Pressed Flower?

(Oshi for push/press(from oshimasu) and bana for flower(from hana))?​

I always that it was for "geeking out about your oshi" like how fans stan their idol together...

(Oshi for idol and bana for talk(from hanashi))​

Or is it like an official translation with some summary?

It's a pun with double meaning. Oshibana is literally the word for the artform/craft of pressed flowers in Japanese. This is also as far as I know as "official" of a translation as it gets since the unofficial doujin on DLSite went with "Pressed Flower / Intermission" although I'm not sure if DLSite staff or the author decided on that one (it wasn't me).

I think your interpretation for the second meaning is correct, but I have no official basis for it. I kept the MangaDex entry as "Oshibana!" for this reason since "Pressed Flower" removes the double entendre.
