Find the name of an ancient romance novel

The male protagonist seemed to have fallen off the cliff because of someone and was saved by the female protagonist. He swore in his heart that his life was saved by the young lady and followed her for the rest of his life. At that time, the female protagonist didn't seem to be under fifteen years old? He's also very good at martial arts, the kind whose parents are masters
The male protagonist has been planning to return to his original home (it seems like a martial arts family) and even went to the study room in the middle of the night to pry open the floor tiles to find the secret manual.
The female protagonist always knew that he was plotting, waiting for him to tell her personally. However, the male protagonist did not say anything, and she was very disappointed and left with her parents.
A few years later, the male protagonist heard the voice of the lady on the street and went to look for the female protagonist. Naturally, he greeted him. Anyway, in the end, the two of them were together
Who knew? Thank you!
