please help me find name of this book

What is the book called????

I am desperate to find out what book it is. I don't know if it's published or on wattpad
halp plas!

The first chapter or one of the first; the girl is at the brothers funeral she ends up walking home without a jacket because she is poor
The brothers friend helps them out with money etc.
At one point he gets hurt and she lets him sleep at the house
There's another point where she is scared and sleeps at the front door holding a knife
The guy has a reputation for being hardcore and he is in charge of some people I think drugs maybe or it wasn't exactly said. And a lot of people are scared or weary of him
The girl has siblings to look after a brother a few years younger then I think 3 more siblings or toddler age or similar

Also in the house some of them sleep on a mattress in the living room and the protagonist was good friends with the brother who died so she is sad about it a lot

Author would be female I think

YA or NA romance. girl who lost brother looks after and siblings and brother's "bad boy" friend helps
