Mars (the main girl seems weak because her appearance and she's quiet but she is insanely strong-hearted and mature. The romance in here is very realistic and mature though, not like common shoujo. There are dark themes)
You should try Kimi Wa Petto (its josei, but basically shoujo but more mature. Its about a strong independent working female and her romance with a younger guy who loves her alot) and also Midnight Secretary (vampire romance betweem boss amd secretary). I believe all of these are on Mangago besides kimi wa petto, you can read it for free on mangareader.com (⌒▽⌒)
All these ladies are strong yet feminine and pretty :)
btw kimi wa petto is actually here on mangago as well if you end up trying it out (⌒▽⌒)
