I don't know if its exactly what your looking for but crazy girl shin bia has a strong female lead and its historical. Its actually one of my favorites. Another one is gu fang bu zi shang manhua. Absolute witch also had a strong female lead. The one manhua also has a strong female lead but in a different sense than the others I mentioned here also its not historical. Another one of my favorite strong female characters is in futsumashi na yome desu ga. She is a perverted main girl. Its really funny because usually its the guy who acts that way. If you like these I can list more if you want.
I actually just thought of the perfect story to recommend. She is a female assassin that gets reborn into a small child from the past. She is seriously strong character and she does fight for the man she loves. Fenglin Tianxia - Wangfei shisansui manhua manga. This one is shounen though.
after reading all these comments i am feeling like i shouldn't read this manga. i don't like sad ending. i don't like weak girl character.
is anyone know.. strong girl character manga who fight for her love , so let me know!!
