So I will recommend you one of my favourite ( BTS Step brothers ) Fanfiction.

MY OVERPROTECTIVE MAFIA
STEPBROTHERS || BTS FF || ✅

[ I know my Phone is very tall even my hands are smaller than my phone 😆]

So this book is written by _Kim_Aura_ . When the book was on its midway. That time I joined the book and started to follow her.

Description of the book :

A girl named y/n cold to everyone except some. She has a horrible past. Her past is the reason of her coldness. What will happen when she would have STEPbrothers and don't know that they are mafias.

Ghostcatcher on this book :

By the way the book shows pure siblings bond between Y/n and her Stepbrother (BTS) . Even her Stepfather loved her like his own daughter. But the mother of Y/n never loved her like her real daughter. Who ever would have knew about her real side they will think is she even her real daughter? How can someone be this cruel.

Ok now enough of these talks. You should go and read this if you didn't read this you will miss a good thing.
