I'm looking for books similar to Hairpin Blossoms. The heroine is clever and clear-headed, the rival isn't dumbed down, and every character is distinctive. Definitely worth a read.
Hua Zhi, who had kept her talents hidden for fifteen years, was forced to reveal her abilities due to a family tragedy. She bravely shouldered heavy responsibilities, and it became her daily routine to show her face in public and ride horses at full speed. She even threatened to kill off her family to protect them, and her reputation as "not to be trifled with" spread throughout the capital.
