Your simulation does not look bad, instead it is not real so it looks good.
If you build it then it will maybe not work or it will sound awful.

I'm not going to build it, just simulation.But I thought there was something to make my signal more beautiful.

ALL audio amplifiers use negative feedback from their output back to the input to reduce distortion and sound beautiful. Yours does not.

What does this negative feedback mean, the sinus to start on the negative side?

Here is a pretty good audio amplifier from Red Circuits. Like ALL audio amplifiers, it has negative feedback produced by R5 from its output back to its input.
It also has C2 so that the DC gain is only 1 then the DC input offset voltage is not amplified.
