Answer 1

This was a classic Mary Sue novel. It usually described a man with a good family background and ordinary appearance who was attracted by the beauty and wisdom of a seemingly ordinary woman and gradually fell in love with her. However, the woman did not know the true identity of the man or knew but was unwilling to reveal it. This plot usually led to a series of complicated emotional entanglements and conspiracies.

This kind of plot was often used in novels not only to attract the interest of the readers, but also to enrich and deepen the emotional experience of the characters. However, in real life, there may be some fictional and unreasonable factors in this plot because factors such as identity and family background can often be difficult to infer directly from the surface.
