Forgotten Title Transmigrated as a mob character

I'm looking for a novel where a girl transmigrates as a mob character and she becomes famous. It's like she's stealing the spotlight from the heroine but not on purpose.

 

There’s a lot of that kind of novel. Can you at least tell if it is JP or CN?

 

Is it somehow wrong for nobody to become somebody ? Does the spotlight somehow belong to the heroine ?

 

I can think of Doomed to be Cannon Fodder. the FMC doesnt really want to compete with the origial heroine.

 

can you elaborate more? Or give some more details, 'cause that's a common troupe in otome genre novels yanno

hmmm will just give some

It's JP.

 

Is it the villainess noble girl type of story?

 

Yup

 

Any extra info like hair color/style or do they use magic? Use broom to fly?
Or meet with a psycho doctor?

 

White Pig or I Will Quit the Entourage of the Villainess, maybe?
