Yes, they are roaming in the martial arts world incognito as Bai Fengxi (FL) and Hei Fengxi (ML) and have known each other for the last 10 years as teenagers but may be unaware of each other's real identity. They may have some suspicion but never outright question it. She is really Princess Feng Xiyun of Qingzhou and he is Prince Feng Lanxi of Yongzhou.

Actually in the novel in addition to the ML there are 6 other men who love the FL including one who did touch her heart before the ML

It's a wonderful story about a very strong and independent FL who is highly skilled in martial arts and the equally skilled ML who loves her. Both FL and ML are kings of their own states and they met as teenagers when they were roaming incognito for 10 years in the martial arts world. Both joined forces to battle against a very aggressive couple from two other states to win the position of emperor of the imperial empire.

Try Maiden Holmes. The FL is very intelligent till the end with a supportive good-looking ML.
