What I find strange is that Romance in Shojo is some of the worst I've ever read, I tried to pick a few random ones a few years back, and I couldn't read any of them, the females are nearly always depicted as weak dreamer types, that are too shy to be interesting and the two love interest usually consist of acomeplte jackarse who gives men a bad name, and the nice guy friend. It becomes obvious the best friend is only there to build tension, and the other guy is going to win.
I've found romance in Shounen is often written better than this, the male charactor isn't a complete arse, the female charactors usually have more depth to them, they have more to them just being a charactor the Male is trying to seduce.
Also why would you look at a manga for females for inspiration when over half your reader base is male? and in all likelyhood the female reader base prefer Shounen over Shojo anyway. Why would you look at inspiation from a genre that is less popular than your own?
I've read some pretty good shojo. The romance in Naruto is honestly terrible; too many unrequited loves. I don't think I've ever read a shounen that had "good romance"... XD If it did have romance it was shown too briefly to count.
However it's no excuse to end any action series with terrible asspulled "romance".
I know for sure so much has inspired me besides the way Naruto was before the ending felt so forced, as well as other anime, manga, comics, etc. for doing it!

. But still Gintama as a manga an anime in therms of everything remains the NO 1 for me . Btw I thought Orihime was the Heroine not Rukia ? Either way from what I've heard and read a little Orihime is what Hinata should have been but sadly they compare Hinata to her bc of BOOBS !
