Why do you think there may be a font? Three very different Es may be telling us it isn't.

And it uses alternatives - like the A

There's a voice ein my head saying this isn't a font because the "e" does not match up the three times it is used. But if you'd like something similar try this Real Kindly https://www.dafont.com/real-kindly.font?text=Sofie+en+Falkert
or Appocalypse - link below.

NOT THE FONT

I think you can fake this by modifying the A.

Google Translate: Je pense que vous pouvez simuler cela en modifiant le A.

It is her actual signature. If you want a clean copy -

Dafont has a Graffiti section - perhaps you can find something similar there to use.

Maybe this will work if you oblique it?

I think this is Bauhaus that was modified by closing up the a and switching the B from another font like Nemesia Bold.

and then obliqued manually.

I don't know the name. But it you would like a quick substitute - take a look at these glyphs

NOT THE FONT

There are so many that look like this. I can't find you an exact - but if you would like a quick substitute try Buttercup. NOT THE FONT - just similar

This looks like the fonts on Creative Market. Maybe someone will find it for you.

and a closer "N" would be this...

ALSO NOT THE FONT

Now if you find an A you can put it altogether.
