Spider Girl and the Lost spider Miraculous (MLB x OC ff)

Mysuteki Sinazuwa.

A not so normal girl, with an even unormal life.

It was hard, really.
Finding out her 'brother' was a bastard baby, when her other had cancer, and she had to move to Paris-
Well she didn't have to...
She needed to. An urge she didn't want to control.
She needed out.

But what happens when in her last few hours, she gets injected by artificial spider poison her friend made, and she gets powers?
What when she moves in, she finds a loose dangly earring, which apparently had powers?
What happens when she catches the eyes of a Ladybug, a cat, a blonde genius, a close emotionless Chinese boy, and a bratty blondie?

!TW!:
-Male Marinette (Marionet), Chloe (Cardan), and Kagami (Kagami)
-Poly relationship
-Bi OC
-Mentions of rape, abuse of any kind, panic attacks, etc.

(Im thinking of making this a Felix, Kagami x reader, but I might add Chloe/ Caleb and the male version of Marinette.)

Read with own caution
