The girl with the strong singing voice is expected to surprise some during the Melodifestivalen's second competition on Saturday night.
For most people, she is probably a completely new acquaintance.
And unlike the competition's more established artists, she also lives a very ordinary life - with a job in the grocery store in Ystad.
- These are very different worlds.
But I have always liked to break a little.
You can sit there and talk to your regulars and the next day you should be on stage, she says.
Colleagues had to line up
Pulling out as a middle star is still not easy when it comes to jigsaw puzzles with everyday life.
There was a little fix that needed to be fixed with the dress and she was needed in Stockholm a day earlier than planned.
Then Green had to rely on her colleagues being able to pull in and take her work shift this week.
And the same goes for Monday.
Actually, she would be back behind the store checkout already then - but it is not possible if she were to scramble to a final place.
Then the morning sofas are waiting for TV instead.
Tips from Anna Bergendahl
But Frida Green also has a strong backing behind her number.
Among the songwriters is Anna Bergendahl who also sang on the original demon.
The former Melodifestival winner has during the week peppered her with tips and tricks for the weekend.
- She sent a very long email a week thinking about this and this.
It was everything from eating breakfast to thinking about this during the camera rope, says Frida Green.
She continues:
- It was just about anything and very good stuff, she is experienced.
Have you checked that you are free in the final now?
- Yes, we can solve that.
I can take some time off, says Frida Green.
