The Bigger Family (A Fgteev Fanfic)

4 boys, Duddy, Chase,Shawn, and Mike.
2 girls, Mommy, and Lexi.
Than when she was young, her dad asked Duddy to take her and act like she was his actual daughter. But at 13 years old, living alone, in a poor cottage, and not knowing what to do with her.
Luckily, his bff Jackson knew and told him. Than years later, at 12 years old, the oldest.
And she thought Duddy and mommy were her real parents.
Atleast she didn't know the story about her parents...
