The first movement has strong dramatic elements, but compared to other sonatas, it is a smaller-scale piece that also features coquettish elements. Of course, it is impossible to literally sing such fast 32nd notes, but it is clear that a song is in the background, so please play with a sense of lyricism.

I consider it not a serious or profound song, but rather an optimistic, joyful, and even alluring one, as if a woman is boasting or showing off her rings and dresses. There are moments with almost no accompaniment where she sings alone (mm. 34-41), and moments where a woman who cannot stop talking continues to chatter (mm. 42-53). Please use your imagination to envision these scenes.

There is also a single sentimental moment (mm. 77-78), but she quickly regains her composure (mm. 83-85) and returns to the original song (m. 88).

Among Mozart's sonatas, this one is relatively easier technically, but some performers put considerable effort into the trills in measures 129-130. While that is fine, to avoid spending too much time there, for example, in measure 129, the performance can be made easier by adding just one extra note per trill, such as CDE GFEFG HAGAH.
